Drills - power and hand 1

Drills and stands

This will enable you to ensure that holes are drilled vertically and square to the wood. It's surprisingly easy, when holding a drill, to produce a hole at an angle.

Drills are the most often used tool in a workshop, for drilling clearance holes, dowel joints or removing a lot of waste from a mortice. However, there are still some jobs which require a hand drill or brace to make larger or deeper holes.

Modern electric drills have a variable speed. This enables a great deal of control and is essential when using, for example, a screwdriver attachment.

Protect your eyes from flying splinters by wearing safety goggles.

Fitting a drill stop

To tell you when a drill bit has bored through wood to a pre-set depth, use a circular metal or rubber stop which fits over the bit., and can be fixed at any point along the shaft. When the stop touches the wood's surface, the bit has reached the correct depth.

Cramp the work

Hold the workpiece securely to stop it moving when drilled. Always place an offcut under the work to protect your bench and reduce splintering when the drill penetrates the workpiece.

Keep the drill vertical with a try square guide when drilling freehand.

A cheap and effective depth gauge can be made from ordinary electrical or masking tape.

Drilling from both sides

drill from both sidesOne of the most common mistakes when drilling is to force the drill bit all the way through a piece of timber from one side. This can be done if the other side of the work is never to be seen. Otherwise the drilled hole should be completed by reversing the work and drilling through from the other side. This will prevent the wood from splintering.

First, fit a spur bit and begin to drill until the tip just breaks through the other face of the wood. Reverse the wood in the jaws of the bench and line up the drill bit with the small hole. Carefully drill through.

A spur bit has a protruding point which penetrates in advance of the main bit.
