Circular Saw Blades

There are two main sizes of blade – 125mm and 150mm. The smaller blade gives a depth of cut of 40mm and the larger 50mm. Circular-saw blades are available in several types and patterns.

Combination type

Suitable for most purposes such as cutting thick or thin hardwoods and softwoods with or across the grain, as well as plywood, blockboard and hardboard.

Cross-cut blades

Cross-cut blades possess fine teeth which cut smoothly across the grain of hardwood and softwood, and are also suitable for cutting plywood, hardboard and block-board.

Rip blades

These are used for coarse cutting with the grain.

Planer blade

Has no sideways ‘set’ to its teeth, and relies on deep, widely spaced gullies for clearing away waste. Gives a neat cut; will saw a variety of thick or thin materials. Planer blades must be kept sharp and must run at maximum revolutions. To avoid clogging, and an overheated motor.

A circular saw allows bends, mitres and grooves to be cut.

The sole plate of the saw is hinged to tilt and allows cuts to be made at any angle between 45° and 90°. Minimum depth is represented at 45° and maximum at 90°. Three basic adjustments for depth, angle and width of cut should always be made and checked before any cutting.
