What is the Best Drill Bit Material
Drill bits are a common type of cutting tool used to
create holes with a circular cross-section from the
objects through removing excess materials, come in
different drill bits sizes for various needs. What are
drill bits made of? In this article, let’s explore the
different types of drill bit materials.
Drill Bit Material Types & Coating - Types of Drill Bits
1. Carbon Steel Drill Bit
– Low carbon steel: this is the cheapest option for
making a drill bit, due to their poor tempers, low carbon
steel drill bits are usually used for drilling softwood
and some plastics, and require to be sharpened often to
extend the lifespan.
– High carbon steel: a better material than low carbon
steel, high carbon steel drill bit can keep their shape
and effectiveness longer, so it can be used to cut
stronger materials, like hardwood and soft metals.
2. High Speed Steel Drill Bit
Compared with carbon steel bits, high-speed steel drill
bit is a more popular choice on the market now. HSS is a
special type of carbon steel, maintaining structural
integrity while bearing high temperature is a marking
advantage of the HSS drill bit, what’s more, high
speed steel bit has higher wear resistance and hardness,
it can also work well at a normal temperature. HSS drill
bits are suitable for most of the wood and metal drilling
process, including CNC drilling. Titanium nitride and
other types of coatings can be applied on the HSS tool to
increase lubricity and reduce friction.
3. Titanium Coated Drill Bit
Titanium is not only a popular aerospace and medical
material, but also a versatile drill bit coating material,
which can make the drill bit last longer. Due to its high
corrosion resistance, good fatigue limit, heat limit,
relatively light weight, and longer service life, titanium
coated drill bit is perfect for repetitive mass production
of drilling into steel, iron, wood, plastic and various
surfaces, it allows a faster RPM and shorter cycle time.
The most common types of titanium coatings are Titanium
Nitride (TiN), Titanium Aluminum Nitride (TiAN) and
Titanium Carbon Nitride (TiCN). TiAN and TiCN are
considered superior to TiN as they can increase the
lifespan to a considerable degree. The drawback of drill
bit coating is that once the tooling becomes blunt, it can
’t be sharpened to avoid the coating material being worn
away.
4. Cobalt Drill Bit
Cobalt is another type of coating for the drill, cobalt
drill bit is used for cutting materials that HSS bit can’
t, such as stainless steel and other difficult materials,
it can retain hardness at much higher temperatures than
HSS and not affected by extremely high heat. But cobalt is
a too brittle coating.
5. Carbide-Tipped Drill Bit
Carbide-Tipped drill bit is very hard, easy to dissipate
heat and can hold an edge longer than other type bits.
Similar to the cobalt drill bit, it’s very brittle as
well and maybe broken up in improper use. Carbide bits are
applicable for drilling fiberglass reinforced plastic and
nonferrous heavy metals.
6. Diamond Drill Bit
Polycrystalline diamond (PCD) is one of the hardest drill
bit material, which can be used on the toughest materials,
such as glass and ceramic. Actually, diamond tool
generally used to grind away material on a micro level, it
can last up 20 times as long as a bare tungsten carbide
tool, but it also cost much higher than any other options.
And diamond bits react negatively when work with ferrous
materials like hot steel.
Drill Bit Material Comparison - What is Best Drill Bit
Material?
The material is a major factor for the drill bit
selection, because it also affects the price, properties
and service life. Are you wondering what is the best drill
bit material for metal, wood, titanium, or steel? Here we
’ll compare some materials.
1. Cobalt vs Carbide, which drill bit to choose?
– Price: cobalt drill bits are cheaper than carbide bits.
– Properties: carbide bits can resist more temperature
than cobalt and HSS.
– Cutting speed: carbide > cobalt
– Application: cobalt bit can drill stainless and
hardened steel, carbide bits are widely used for drilling
nonferrous heavy metals, cast iron and abrasive materials.
2. Cobalt vs Titanium, which drill bit is better?
– Composition: titanium bits are made of carbon steel or
high speed steel with TiN, TiAN or TiCN coating, cobalt
bits are HSS bits with cobalt in alloy.
– Application: titanium coated drill bits can make the
tool last longer and reduce temperature when cutting
plastic and wood, the cobalt bits are intended for
stainless steel and hardened alloy steel.
3. HSS vs Cobalt, what’s the difference?
– Price: in general, HSS is cheaper.
– Properties: cobalt bit has higher strength and wear
resistance, however, it’s more brittle than HSS as well.
– Application: high-speed drill bits are suitable for
drilling plastic, wood and mild steel, cobalt, which is
the option for drilling tough materials, it also can do
the work what HSS bit does.
GUIDE TO CUTTING WHEELS
In metal fabrication and manufacturing operations, various
tools use cutting wheels to cut material from a workpiece.
What is a cutting wheel? Cutting wheels, or cut-off
wheels, differ from grinding wheels in their function and
structure. Where grinding wheels use an abrasive to grind
large pieces of material off a workpiece from a shallow
angle, cutting wheels typically make narrow, precise cuts
at 90-degree angles. Consequently, cutting wheels are
often thinner than grinding wheels — though they do not
have the lateral strength required for side grinding,
their minimal thickness makes them better for clean,
accurate cuts.
Weiler Abrasives offers several cutting wheels for
different applications. We provide everything from 1-
millimeter cutting wheels to extended-diameter wheels for
larger cuts. This guide to cutting wheel covers the
differences between various types of cutting wheels and
explains how to choose the right wheel for a given
application.
How to Use a Hole Saw
Cutting a perfect circle in wood doesn't need to be
difficult! There are numerous ways to accomplish this
task, depending on the tools you have in your garage. The
easiest one to use is a circle shaped saw, named simply, a
hole saw.
Ill explain the parts of the hole saw as well as some
techniques for using them. By the end of this article, you
should feel confident wielding this tool on your next
project.
Spade bits are useful for projects where you need a small
hole drilled quickly, like when youre running wiring
through a stud wall. Theyre the cheapest option of the
three, but they have some downsides.
First, the spade bit can be hard to use near the edge
of a board. They also dont make the cleanest hole and tend
to tear out. In general, this type of a bit is best for
rough construction rather than a fine woodworking project.
WHAT IS A HOLE SAW?
A hole saw
makes both a hole and a round wooden disc with a thin
serrated blade around a central drill bit.
Hole saws can be attached to a regular cordless drill or a
drill press. There are many types and sizes, which can be
used for cutting wood, concrete, tile, and even metal.
How can this tool help you? Here are some common projects
you might need a hole saw for:
Doorknob and light fixture hardware - Door knobs and light
fixtures require a precise hole for proper placement. Most
other methods for cutting a circle wont work on a door or
ceiling, so a hole saw will be a great help.
Plumbing and ductwork - Hole saws can cut more than just
wood. You can use one when installing ductwork, or to hook
up a rain barrel to your downspout.
Crafts - Dont struggle with lopsided circles made with a
jigsaw! Its much easier create the hole in a cornhole
board, or to make giant Lego dots on the side of a DIY
Lego table with a hole saw instead.
SPADE BIT VS HOLE SAW
Use a spade bit instead of a hole saw to bore up to 1 ?
holes in wood when you dont need the plug and dont mind
the rough cut edges. Spade bits have two sharp edges with
a point in the center. As the bit spins, the edges shave
out the wood.

Tips to Choose the Perfect Concrete Hole Saw
Do you own a concrete table top, or foundation that you
have set along the bathroom or room surface at your home?
Need to drill through it to create a vent or for some kind
of fixture? You need the right hole saw that can fit the
shape of your drill and make itself comfortable in your
home. Getting the perfect concrete hole saw
needs a little choosing before buying.
Why Hole Saw
Hole saws are supposed to be slower than a boring bit that
apparently does the same work of drilling into your
concrete. But while boring bits are a bit expensive, hole
saws are available easily at a cheaper rates. The 3 inch
concrete hole saw would work perfectly with the 3/8” home
drill that you use to drill into the concrete. This is
probably why most homes prefer hole saw to drill their
concrete settings.
Know the Hole Saw
When you plan to dig a bigger hole in the concrete to set
up your plumbing stations or probably just want some work
done on your concrete, you should use a hole saw. It is a
steel cylinder which has a saw tooth at the top edge. This
saw tooth cuts into the concrete basing out exactly the
shape that you desire.
Choosing the Hole Saw
It is very important to choose the perfect hole saw to
drill your concrete. You can get a carbon steel hole saw
at a perfectly cheap rate. This is generally used to cut
wood though. Your bimetal hole saw is practically used to
cut both wood and metal. But when you are looking to cut
through concrete, you need to think of buying a diamond or
carborundum grit 3 inch hole saw. This will cut through
the concrete perfectly.
Using the Hole Saw
When you are working on concrete with concrete hole saw,
here’s how you do it. You should draw a huge circle
around the area you are looking to drill. Now begin
drilling with your hammer drill; you need to punch holes
in here. Once you are done with that, you can clean the
whole setup with a side grinder or a diamond blade. You
can use the spline shafted with the hole saw to do the
whole drilling for you. Make sure you use a 2 and half
inch spline for the drilling purpose. This will blend in
easily.
Breaking In Your Diamond Saw Blade
One key to ensuring a long life and ease of use for
diamond saw blade is knowing how to properly
prepare them for use.
First, make several cuts through a soft abrasive material,
such as a common red brick.
To start a saw cut on lapidary material, run the saw blade
at operating speed and slowly feed your stone into the
spinning blade. Watch the initial cut to ensure a straight
feed. If the cut isn’t straight, the blade will deflect
at the point of contact, producing an uneven cut.
As soon as you notice the blade deflecting, stop the saw,
shift the stone slightly and start the process again. If
you don’t correct the process immediately and continue to
cut, the blade will be dished by the time you finish the
cut. If this happens, the blade will require repair or
replacement.
As a professional
manufacturer, we offers a variety of lapidary
equipment and supplies for jewelers and stone cutters.
