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.

Questions about this item
Does the carbon steel 25 mm bit overheat when drilling plywood all day?
The bits are heat-treated carbon steel with polished surfaces for wear resistance; keep the drill vertical, run moderate speed and pause to cool for longest life.
What chuck does my drill need for the 1/4 in hex shank?
A 1/4 in hex chuck or quick-change chuck accepts the universal hex shank on every bit in the set.
Will the 10 mm and 12 mm bits work in my older 1/4 in hex impact driver?
Yes, the 1/4 in hex shank fits most current and older drills, including bench drills, corded and cordless hand drills.
