CAN CUT THROUGH TOUGH MATERIALS
These bits create smooth, burr-free edges without smearing and are perfect for chamfering and countersinking holes on soft metal, steel, iron, wood, and plastic.
CROSS-HOLE, ZERO FLUTE DESIGN
The bits have no flutes and instead of sharpened cutting edges, they have a hole bored through their cones at an angle. As the bits spin, the trailing edges of their holes make the cut.
Constructed with high-speed steel and coated with super-hard titanium, these bits have the durability to withstand high-heat conditions for lasting use.
4 PIECE PER SET
The set includes four drill bits with sizes ranging from 2-5mm, 5-10mm, 10-15mm, and 15-20mm to meet all your drilling needs.
