Description:
1. The high speed steel tool is good for most general applications, with a combination of hardness and toughness for wear resistance.
2. Reduced shank drill extends the size range of a portable drill chuck. Common groove and total length for minimal adjustment when changing tools.
3. Polished treatment adds lubricity. Small pockets on the surface of the tool, keep coolant near the blade.
4. Design for drilling in low and medium tensile strength materials such as aluminium, iron, copper, brass and metal. Reduced shank drill is widely suitable for woodworking (hardness of the material to be drilled should not exceed 29HRC).
5. Anti-clockwise (right-hand cutting), spiral ridged tool removes chips up and out of the cut to reduce blockage.

Box contents:
1 x Reduced Shank Drill Bit

Instructions for use:
1. To make clean and precise holes, water is required for lubrication and cooling when drilling metals. The feed speed should also be controlled.
2. Low drilling pressure and increased use of water lubrication extend the life of the drill.
