Makita D-64347 HSS-Tin Metal Drill 5.5-93 10Pcs. HSS drill bits with 5% cobalt content and high-temperature brazing for easy drilling of high alloy or high tensile steels. Body ground for further accuracy and to reduce resistance. Use on mild, stainless, and high alloy steels and difficult to machine materials, welded seams, and car bodywork. Ideal for stainless steel and aluminum.
- Titanium-nitride coating reduces friction, increased heat resistance and corrosion resistance
- Can be operated at higher drilling speeds versus cobalt and black-oxide bits
- 135o split point tip geometry prevents bit walking for fast and accurate material penetration
- Half-ground edge and flute construction for high quality performance and long life
