Kit Includes 1/8", 5/32", 5/16", 3/8" "TiN" coated drill bits
Our Kits are a SIGNIFICANT UPGRADE to any kits on the market.
AGT's "TiN' coated (Titanium Nitride) high speed steel drill bits were specifically designed for drilling # 6061 and # 7075 aluminum. Don't be "FOOLED" by our competition selling drill bits (with fancy names) coated with coatings not made for drilling in aluminum.
