There are a number of different types of chisels and drill bits, all perfectly designed for a particular use. Here is a quick introduction to the most common types of both, to help select the perfect one for any job.
Types of chisel
Bevel-edged chisel – This includes a slightly undercut blade, which helps with chiseling off wood from corner surfaces. It is perfect for use when finishing dovetails.
Firmer-edged chisel – The blade on this has a rectangular cross-section, providing greater strength. The design makes them ideal for heavier going and generally tougher work.
Paring chisel – A long and thin design makes this ideal for finishing. The dimensions of the blade allow this to be perfectly used for cleaning joint and working wood to a more accurate fit.
Having decided on the blade of the tool, it will also be necessary to select the best handle. This is very much one of personal preference, with them made from woods such as ash and beech or modern plastics. It is also important to remember a mallet should be used, as opposed to a hammer.
Types of drill bit
Twist drill bit – Available in a range of sizes, these are ideal for drilling into all sorts of basic surface. Slowly increasing the diameter of the bit will ensure the perfect hole is provided each time.
Masonry bit – Also available in a number of different sizes, these are made from carbide steel for greater strength and durability. Ideal for brick and stone, they will need regular grinding to a point.
Hole saw – With a serrated edge, these provide a perfect way to cut through wood boards. Smooth operation is needed here, to ensure no jamming occurs and chippings escape thoroughly.
Other options to look out for include, flat bits, plug cutters and Forsner bits for blind hole cutting. The best quality are those made from high-grade steel, engineered for high speeds.
