About this item
  • [Package content]- 6 Pcs 3mm Drill Dia High Speed Steel straight shank twist drills.
  • [Strength and Hardness]- Made of high-speed 6542 steel, rock wall hardness grade HRC 63-66. With black oxide coating treatment, it is reliable and durable.
  • [Professional and DIY use]- Suitable for hardened materials and hard metals, such as cast iron, hard plastics, and also suitable for soft materials. When it cannot penetrate, try to adjust the RPM.
  • [Twisted Design]- With a 120° angle point and twist design, it can increase the cutting speed through automatic centering; avoid displacement during the work process, and at the same time remove debris and particles faster and easier. The straight shank can be firmly fixed and accurately centered, suitable for standard drill chucks and conventional round chucks.
  • [Note]- Please keep cool and gentle using, the working life of the twist drill bits can be largely prolonged by proper usage

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

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.
