Hole Saws - Bi-Metal FCH (Fast Cut)

Starrett FCH (Fast Cut) bi-metal hole saws are designed for speed. An aggressive tooth geometry gives faster cutting without sacrificing edge life or cut quality, which makes them ideal for tradespeople drilling high volumes of holes. Typical materials are wood, plasterboard and thin metal: think first-fix electrical and plumbing work, kitchen and bathroom fitting, and installing downlights and fittings. The range runs from 14mm to 210mm, and selected sizes are available in a pack of 6 as well as singly. If you drill the same size repeatedly, the pack of 6 keeps a sharp hole saw to hand. How to choose between FCH and other hole saws: choose FCH when speed through wood, plasterboard and thin metal matters most; choose the DCH range for extra cutting depth; and choose a carbide-tipped range for abrasive or nail-embedded materials. Usage tips: let the aggressive teeth do the work rather than pushing hard, reduce the speed for larger diameters and clear the core between holes to keep cutting fast. Is a fast-cut hole saw rougher? The FCH tooth geometry is designed for speed without sacrificing cut quality, so it suits everyday trade holes in common materials. Should I buy singles or a pack of 6? Singles suit occasional sizes; the pack of 6 suits sizes you use on every job.
