Characteristics of a compass saw
– Narrow, tapered blade with a sharp point
– Tooth pitch ranges from 2.5 to 3 mm for most materials
– Tooth pitch can be as low as 1.3 mm for harder materials
– Tooth pitch can be as high as 5 mm for softer materials
– Curved, light pistol grip handle for confined spaces and overhead work
Comparison with other types of saws
– Larger blade and longer pitch compared to coping or fretsaws
– Allows for faster cutting and cutting through thicker materials
– Leaves a rougher finish compared to coping or fretsaws
– Longer blade and shorter pitch compared to drywall saws
– Keyhole saws have shorter, finer blades and straight handles for cutting tight curves
Uses of a compass saw
– Suitable for cutting softer woods, plastic, drywall, and non-ferrous metals
– Pointed tip can penetrate softer materials without a pilot hole
– Blade can be fixed or retractable
– Interchangeable blades are common
– Partially retracting the blade prevents flexing and breaking when cutting harder materials
