Hyamass 6-piece spade drill bit set 10–25 mm

Hyamass 6-piece spade bit set 10–25 mm

This Hyamass set contains six carbon-steel spade bits sized 10 mm, 12 mm, 16 mm, 18 mm, 20 mm and 25 mm. Each bit has a 1/4-inch hex shank that locks into quick-change chucks on most corded or cordless drills. The flat paddle head with double cutting spurs is designed for clean holes in wood, fiberglass, PVC and soft plastics. It suits both DIY enthusiasts and professional woodworkers.

Sustained drilling performance

The heat-treated carbon steel resists wear during repeated cuts in plywood, particle board and fibre board. Double side cutting spurs help maintain cutting speed and smooth chip removal over long sessions. Keeping the drill vertical and moderating speed prevents overheating and extends bit life. The bits are not intended for hard metal or masonry work.

Compatibility checklist

Verify your drill accepts a 1/4-inch hex shank before ordering. Ensure the 150 mm overall length clears your workpiece and chuck. Confirm the material you plan to drill is wood, fiberglass, PVC or soft plastic — not structural steel or concrete. Check that the six diameters cover the hole sizes your project requires.
