About this item
- ★ Drill Bit Size --- Cutting edge diameter: 30mm / 1.18"; shank diameter: 1/2"; effective cutting edge length: 60mm / 2.36"; cutting edge length: 79mm / 3.11"; overall length: 150mm / 5.9"; hardness: HRC62-63; cutting direction: right hand.
- ★ Wide Applications --- Suitable for drilling common soft materials such as aluminum, copper, cork (soft wood), plaster, plastic, rubber, etc.. Reduced shank drill bits expand the size range capacity of portable drill chucks.
- ★ Spiral Flutes --- Sharp spiral flutes provide fast, neat and smooth cuts. The spiral groove facilitates the export of metal chips, which saves time and effort in operation. Designed with small pockets to keep coolant near the cutting edge.
- ★ High Speed Steel --- The twist drill bit is made of 4241 high-speed steel, with high hardness, good toughness, high strength, and wear resistance. Polishing reduces surface roughness for a smooth, flat surface.
- ★ Useful Tips --- Use on drill presses and bench drills. The appropriate lubricant is beneficial for cutting or cooling, improving dimensional accuracy and extending tool life. Reduce forward and reverse speed. Use harder aluminum and wood.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
