Premium Quality Design:
- Made from high quality alloy blade, hardened and tempered, carbon HSS steel construction.
- The blade is characterized by high accuracy, smooth cutting operation, good resistance to shock and good toughness.
- The head adopt arc curve design, beneficial to chip removal, perforation is more efficient.
- 2 spurs and 2 precision ground cutting edges design, long-lasting cutting performance.
Great Woodworking Tool Set:
- In design with curve, the head is good at removing the debris and working efficiently.
- The tip is specially designed to cut through hole cleanly, great for boring concealed hinges and door locks.
- Guided by the Circular Rim, Bores Any Arc of a Circle, in any direction, great for drilling flat bottom holes, pocket holes, or overlapping holes.
- Precision ground for heavy use and easily resharpened, they can enlarge existing holes with ease and can bore any arc of a circle.
- Can be used for wood products perforation, mounted spherical door shoot tip, drawer, plastic products, wood, plywood, etc.
- Suitable for pistol drill, bench drill, vertical drilling machine hand held electric drill, stand motor-driven drilling machine and mobile ribbon type magnetism drilling machine, etc.
