Specification
Brand : LIBRATON
BulletPoint : Taper Shank Drill Bits
BulletPoint1 : 4-Flute Turbo-Cutting System: Libraton step drill bit set has quad spiral grooves enabling 40% faster chip evacuation than 2-flute competitors, eliminating jams when drilling.
BulletPoint2 : Military-Grade M35 Cobalt Core: Our step drill bit for metal is of 5% cobalt alloy withstands 1,450°F heat - 3X lifespan vs normal HSS bits. Perfect for hardened steel, copper alloys, and carbon fiber composites.
BulletPoint3 : Nano-AlTiN Armor Coating: The unibit step drill bit is of 89HRC-rated surface with 0.45 friction coefficient outlasts TiN coatings.
BulletPoint4 : Universal 1/4" Hex Shank: Each step bit has instant compatibility with multiple tools. Anti-slip grooves prevent chuck slippage even under 35N·m torque.
BulletPoint5 : 34 Step Sizes: There are 3PCS step drill bits, and the step drill sizes range from 1/8" to 7/8" in 0.04" increments. The step drill bit set includes a shockproof case, easy to store and carry.

ProductDescription : ·Our step drill bit is easy to use, one drill can drill holes of multiple specifications
·The step bits can be used for a variety of materials such as iron, copper, aluminum, plastic, wood, etc. (Please note that it is not recommended to use it for aluminum plates. Aluminum chips get hot and easily stick to the drill bit during drilling, affecting drilling efficiency)
·Libraton step drill bit for metal is of overall high-speed steel M35 material contains Co 5%, high hardness, and the matrix hardness is HRC64-67. Improve the life of the product (the commonly used drill bit materials on the market are 4241/4341/9341/6542/M35/M42, and their performance increases in turn.)
·AlTiN surface coating, the hardness can reach HRC89, which is 5 times higher than ordinary products and 30% higher than TiAlN coating. Increase wear resistance and reduce friction
·The unibit step drill bit is of Four-edge spiral design improves chip removal speed, higher cutting efficiency, and smoother. The four-edged blade is stable and easy to control, which can reduce the deflection problem of the drill bit during cutting and make the hole more round
·Hexagonal shank interface, which can be used for both electric drills and electric screwdrivers
·The head angle is 118°, which can reduce the pressure required for center positioning and effectively prevent movement during use

-How to use a step drill bit: Ensure the chuck is securely tightened on the power tool. Use low speed and apply light pressure on the workpiece until reaching the desired depth. Lubricate the cutting edge with oil or a water-soluble lubricant to reduce friction, heat, and debris.
