For high tensile steel, fits in a 3/8" chuck
Our SST+ 3/8" reduced shank drill bits allow for the drilling of larger holes with drills that have a 3/8" chuck capacity. Their 135° self-centering split point allows for outstanding performance with much less pressure.
Features:
Made with premium grade cobalt HSS to drill harder materials
Self centering 135° split-point for reduced thrust requirements and minimized walking
Cobalt drills can drill approximately 30% faster than HSS drills
Special bronze SST surface treatment for extreme lubricity and life
3/8" reduced shank
3-flats shank for reduced slippage in drill chucks
Applications:
Drilling holes in high strength materials
Heavy-duty drilling
Drilling large diameter holes
Drilling with handheld power tools
Tech Tips:
Speed, feed, and lube are all critical to cutting tool performance
