2The Pillar DrillThe Pillar Drill can be used to drill wood, metal, and plastic. As a general rule the larger the hole you are trying to drill the slower the drill should rotate.When using this (or any other machine) it is important to read the safety notice on the wall to make sure you understand how to use the machine safely.When using the Pillar Drill you mustWear GogglesTie any long hair backTuck in any loose clothing

6Drill Bits Twist Drills 2) Reduced Shank Twist Drill (Used for drilling wood, metal and plastic)2) Reduced Shank Twist Drill(As above but reduced shank allows larger drill bits to be fitted in a chuck)3) Dowel bit(Used to drill clean holes in wood for dowel joints)4) Spade Bit(Used for drilling large holes in wood)5) Masonry Bit(Used to drill holes in concrete)6) Forstner Bit(Used to drill clean flat bottomed holes in wood. Available in a wide range of sizes 6 – 50mm)
7Twist DrillsTwist Drills are available in a wide range of sizes. In the school workshop they range from 1, 1.5, 2, 2.5, 3, ……….12.5, 13mmThey are used to drill wood, metal and plastic.
8Drilling Metals Machine Vice When using a twist drill to drill metal you must always secure the work piece in a vice. For large pieces of metal you can use a Machine Vice and for smaller pieces a Hand ViceHand ViceRemember when drilling large holes always set the drill to a slow speed. If the holes are bigger than 10mm it is generally safer to drill a Pilot Hole first.(A pilot hole is a smaller hole, say 5mm, that will act as a guide for the larger drill)
9Drilling Plastic Machine Vice When using a twist drill to drill plastic you should always try to secure the work piece in a vice.Remember when drilling Acrylic don’t try to drill too fast or the brittle plastic could shatter.Make sure you tighten the vice properly or the work piece may come loose(This is true for drilling all materials)
10Drilling Wood Machine Vice For drilling smaller pieces of wood you should use a machine viceWhen drilling larger pieces of wood it is safe to hold the wood securely with your hand
11Flat Bits Flat bits are available in a wide range of sizes. Flat bits are used for drilling holes in wood only. The main advantage flat bits have over other types of drill are.They are easy to sharpenThey cost less.
12Forstner BitsAs shown below Forstner bits are available in a wide range of sizes.Forstner bits are used for drilling holes in wood only. The main advantages of this type of drill bit are.Forstner Bits produce a very smooth cut that requires little finishing.Forstner Bits produce a flat bottomed hole.
13Plug Cutters In the workshop we have 3 sizes of plug cutter. 6mm, 9mm, & 12mm.These can be used to cut small wooden plugs as shown.PlugCutters
14Using a Plug Cutter Flush Cut Saw 5) When the glue is dry use a flush cut saw to trim the excess plug6) Sand Smooth3) Use the appropriate Forstner bit to drill a hole in to work piece that is to be plugged.1) Using a pillar Drill and Machine Vice carefully drill a plug about 10mm deep2) Use a screwdriver to break the plug loose.4) Glue the plug in place
15Hole Saws Scrap Hole Saw Hole saws can be used to cut hole in thin sheet material. (Wood, Metal and Plastic) This tool is traditionally used by Plumbers to drill holes in water tanks etc. (When drilling metal oil must be used to help keep the blade cool and the work piece must be clamped to the table)ScrapHole SawAs you can see from the shape of the scrap wood the hole saw can also be used to make wheels.
16Counter Sink BitThe Countersink Bit is used to countersink holes for countersunk screwsThe Countersink bit can be used in a hand drill, pillar drill or Cordless drillCountersink Bit
17Hand Drill The Hand Drill can be used to drill small holes (up to 8mm) And is useful for holding a countersink bit
18How to screw two pieces of wood together Countersink Bit1) Drill a pilot hole2) Counterbore the top piece3) Countersink the top piece4) Drive in a screwHand DrillPozi Drive Screwdrivers
19Carpenters Brace & Bit Brace Chuck Auger Bit Ratchet The Carpenters Brace can be used to drill large diameter holes through wood. Auger Bits are available in a wide range of Lengths and Diameters
20Carpenters Brace & Bit Handle Ratchet The ratchet mechanism allows you to drill a hole where the sweep of the handle is otherwise restricted (in a corner or beside a wall)
21Carpenters Brace & BitThe Carpenters Brace is used as shown in the picture on the left.DamageOne of the main problems with this type of drill is the damage that can occur to your work piece when the Auger bit exits the wood.
22Carpenters Brace & Bit Scrap Wood This can be overcome in two ways By drilling in from both sidesBy putting a piece of scrap wood behind the work piece
23Auger Bits Expansive Bit Maximum Setting Minimum Setting Another type of drill bit that can be very useful is an Expansive Bit. This type of bit has an adjustable cutter that can drill a wide range of different sized holes.The Auger Bit has a square taper shank. This can only be fitted into a Carpenters Brace.
24Masonry Bits 4kg SDS Hammer Drill Masonry drills are used to drill holes in concrete. They are generally made from toughened steel with a Tungsten tip.The picture above shows a powerful hammer drill suitable for drilling large holes in concrete.Tungsten Tip
