Home Improvement By Highfire

• Sharp Cutting Edge - HIGHFIRE hex shank drill bit set has accurate tip geometry which ensures cutting edge sharp and strong. 135 degrees split point tip provides a no-walking drilling start on working surface.
• Hex Shank Bits- Hex shank drill bits fit in quick-change impact drivers. Hex shank eliminates shank spinning in chuck when using pressure.
• Solid Connection and Tapered Web - The strong connection of drill bits and shank transits high torque from drills to the tip of the drill bit without breakage. It also decreases radial runout to make the hole rounder. HIGHFIRE hex shank drill bits with tapered web design increases strength and reduces breakage.
• Twist Flute and Titanium Coating - With optimized flute form, HIGHFIRE drill bit decreases friction and heat easily to ensure fast drilling and a long working life. 135-degree twist flute helps to remove chips quickly. TiN coating extends drill bits life 3 times longer.
• Wide Application - HIGHFIRE drill bits are built for general purpose, such as DIY projects, maintenances, repairs and operations. Working materials include steel, copper, aluminum and zinc alloy. They are ideal metal drill bits for steel.

• TiALN COATING: TiALN coating has excellent characteristics such as high hardness, high oxidation temperature, strong adhesion, small friction coefficient and low thermal conductivity. TiALN coated cutting tools can be used for hard materials and high speed cutting.
• THREE FLUTES STEP DRILL BIT: Ordinary step drill bits are prone to deflection during cutting, but three flutes step drill bits are more stable. The service life of three flutes step drill bit is twice as long as that of ordinary step drill bits; the drilling accuracy is significantly improved; and the cutting efficiency is much higher than ordinary ones.
• M35 COBALT: M35 cobalt HSS step drill bits are more suitable for hard working materials, particularly adapt to drill stainless steel, cast iron, high temperature alloy, titanium alloy and even hard plastics and woods. And a must-have for handyman or professionals, perfect for home repairs and light jobs.
• HEX SHANK: 1/4\" hex shank is easy to be installed on impact driver, quick change. And eliminates shank spinning in drill chuck. The step drill bits set for metal are suitable for home DIY, general building and engineering uses.
• STEP DRILL BITS SIZE: 1 pc 9-step (1/4\", 5/16\", 3/8\", 7/16\", 1/2\", 9/16\", 5/8\", 11/16\", 3/4\") drill bit, 1 pc13-step (1/8\", 5/32\", 3/16\", 7/32\", 1/4\", 9/32\", 5/16\", 11/32\", 3/8\", 13/32\", 7/16\", 15/32\", 1/2\") drill bit, 1 pc 12-step (3/16\",1/4\", 5/16\", 3/8\", 7/16\",1/2\", 9/16\", 5/8\", 11/16\", 3/4\",13/16\", 7/8\") drill bit. All the cone bits come in a well organized case for easy transport and storage.
