Drill Bit Sharpening Angle Chart: Metal, Wood, and Masonry Bits

Drill bit sharpening angle is important to cut and remove the material in an efficient way. Drill bits should be sharpened according to the hardness of the drilling materials. Metal and wood drill bits should be sharpened between 118 degrees and 135 degrees. 118-degree drill bits are suitable for soft materials, and 135-degree drill bits are suitable for the harder materials of any type of metal and wood. For the concrete, tile, and bricks you should have 100°-115°. For the PVC and fiber, you should have 50°-65°.

You can use a drill bit angle gauge to measure the drill bit angle properly while you are sharpening it. Using the below drill bit angle chart you can sharpen any type of drill bit to drill wood, metal, concrete, brick, tile, PVC, and fibre.

How to Measure Drill Bit Angle?

When you sharpen the drill bit, its angle should be measured correctly. Because the material removal rate depends on the drill bit angle. When the drill bit is dull or wandered, you should resharpen it properly. You can use a drill bit angle gauge.

If you need to measure drill bit angle frequently, a fixed drillbit sharpening gauge is efficient. You can use an adjustable gauge to measure the wide range of drill bit point angles.

You should measure the drill bit angle 3 times during the sharpening process.

  1. Before you start the sharpening process – To understand the variations and wandering of the drill bit.
  2. During the sharpening process – To makesure, it is sharpening well
  3. Finally – You can make sure the drill bit has properly sharpened using the gauge.

Drill Bit Angle for Metal

The metal drill bits should have a below drill bit angle every time. When you sharpen metal drill bits make sure to maintain these angle sizes.

High Tensile Steel130°- 135°
Stainless Steel130°- 135°
Tough Steel135 – 140
Sheet Steel130°- 135°
Brass, Bronze118°

Drill Bit Angle for Wood

The wood drill bit point angle typically ranges from 118 degrees to 135 degrees. The most common angle for wood drill bits is 118 degrees, while larger bits may have a point angle of 135 degrees.

The angle of the drill bit affects how well it can cut through wood and how long it will last before it needs to be sharpened. A steeper angle can provide faster and more aggressive cutting. For the softwood, we should use 118 degrees of the drill bit with a deep flute.

For the hardwood, we can use a 135-degree drill bit. It helps to slow penetration into the wood without too much heat. A shallower angle may provide a slower cut, but it can also lead to a longer lifespan for the bit. Ultimately, the choice of angle will depend on the type of wood being drilled and the desired result.

Drill Bit Angle For Concrete, Stone, and Bricks

Concrete, stone and bricks are harder materials. When you need to drill them, you should use a masonry drill bit. A masonry drill bit point angle should be between 100 degrees and 115 degrees. For the wider drill bits, the point angle should be higher than the small drill bits.

In order to withstand the hammering action, the drill bit point angle should be wider. Else drill bit tip will damage easily. When you use a tile drill bit its point angle should be between 50 degrees and 65 degrees. These tools can withstand friction rather than hammering action. Hence lower angle is always better than a wide angle.

A drill bit angle is very useful while it is resharpening. A proper drill bit angle can cut and remove materials easily. A steep drill bit angle has an aggressive cutting speed and a wider angle has a slower cutting speed. When you resharpen the drill bit, you should maintain the drill bit angle properly.

Hi, I am Tom Mackency. It has been 10 years that I have been working as a professional woodworker since 2013. I am really enjoying my carrier by creating many kinds of projects in my workshop. But mostly I like for home improvement projects. Home improvement and DIY projects are the most interesting things for me. More than that, the coolest things are power tools. Those are very precious and efficient than a decade ago. So I try to introduce so many things about power tools, woodworking, DIY projects, home improvement and many more interesting topics here.
