WHAT IT DOES

A variety of drill bits are used to drill holes in wood, concrete, metal and plastic. Each drill bit will differ.

Here is an intro to 22 different types of drill bits to illustrate the idea! https://www.theengineerspost.com/types-of-drill-bits.

Basic rules of thumb:

House-shaped tips are for masonry (brick, block, stone, concrete)

Black lip and spur bits have a central point for accurate drilling in wood

High speed steel (HSS) is sometimes coated in titanium or cobalt for a hard cutting tip and longer life, specifically used in metal primarily. Use a cutting oil (3 in 1) to aid cutting

HSS bits, step drills, holesaws, and spade bits are also used in plastic and wood

Drill bits of various sizes and uses. Not as many bits as there are in the original photo!

SAFETY INFORMATION & PPE

Safety glasses – Essential

Ear protection – Recommended

Observe the safety instructions and PPE usage of the tool being used with the drill bits.

YOU MAY ALSO NEED

Pencil, Ruler, Set Square – Essential to mark your workpiece. Measure twice, cut once!

Clamps – Useful to hold your work securely in place and prevent it from moving.

Workbench and/or trestles – Useful to not break your back.

HOW TO USE IT

Not sure about the size? Start with a small drill bit size, and work your way up.

When drilling masonry, sometimes masonry is soft, so start without the hammer action and use it in bursts afterwards if need be.

Smaller drill bits on softer materials work with faster speeds (usually speed 2 on a combi drill). Larger bits require slower speeds (often 1 on a combi drill)
