Features

• Carbide small-diameter coating drill with ultra-high speed, long life, and hole drilling realized by unique cutting edge shape (patented: Patent No. 5800477) and groove shape.
• The two-step angle at the tip significantly reduces shoulder wear and blurring compared to conventional drills, and greatly improves performance not only in high-speed use.
• The unique groove shape significantly increases the efficiency of chip removal during high feed, and also prevents breakage of the drill due to shoulder chipping, not only during high-speed use.
• Work Material: Carbon Steel, Alloy Steel, Stainless Steel, Mild Steel, Tempered Steel, Cast Iron, Tag Tile Cast Iron, Tool Steel (~HRC40), Titanium Alloy.
