WHAT IT DOES

Variety box of drill bits 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) are 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, spade bits are also used in plastic and wood
  • Before deciding on the correct bit for your task, make sure you pick the correct hand or power drill or driver. See the guide ‘Choosing power drills and drivers’ to help you with that: https://edinburghtoollibrary.org.uk/guides/#drill

    Hex bit holder plus 11 small driver heads, 11 long driver heads, a counter sink, 4 hex adaptors in 8, 10, 12 and 13mm, and three drill bits in 2, 3 and 4mm.

    Please review images for bit codes. Also, please be gentle with the case! The plastic is getting old and somewhat brittle, and half the hinge is already fractured.

    SAFETY INFORMATION & PPE
    • Safety glassesEssential
    • Ear protectionRecommended
    Observe the safety instructions and PPE usage of the tool being used with the drill bits.

    • Pencil, Ruler, Set SquareEssential to mark your workpiece. Measure twice, cut once!
    • ClampsUseful to hold your work securely in place and prevent it from moving.
    • Workbench and/or trestlesUseful 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)
