SALI Twisted Drill Bit

Feature:
1. Industrial-Grade M35 Cobalt Steel Construction
Each drill bit is manufactured from M35 high-speed steel alloyed with 5% cobalt.This composition significantly enhances heat resistance and surface hardness, allowing the bits to maintain their cutting edge even under high-speed, high-stress drilling conditions.The bits retain hardness at elevated temperatures, enabling higher drilling speeds compared to conventional HSS bits.Users consistently report clean holes through hardened materials with no perceptible dulling even after multiple uses.
2. 135° Split-Point Tip for Precision Starting
The specially engineered 135° split-point tip ensures instant engagement with the workpiece surface.This design eliminates "walking" or skidding across the material, so you can start drilling precisely where you intend-without the need for a center punch.The result is faster, more accurate drilling with less force required, reducing user fatigue and improving work quality.
3. Parabolic Flute Design for Rapid Chip Evacuation
The bits feature a precision parabolic flute geometry that facilitates quick and efficient chip removal.This design reduces friction and heat buildup during extended drilling operations, prolonging bit life and maintaining cutting performance.The sharp cutting edges enable smooth, effortless cutting through both wood and metal.
4. 1/4" Hex Shank with Quick-Change Compatibility
The 1/4-inch hexagonal shank is engineered to withstand high torque transmission and heavy pressure.Fully compatible with standard and quick-change chucks, as well as impact drivers.The quick-change design allows for tool-free, rapid bit swaps-seamlessly transition from drilling to driving to keep your workflow moving efficiently.The hex shank also prevents slippage in the chuck, ensuring secure bit retention during demanding applications.

5. Versatile Multi-Material Performance
This set is engineered to drill cleanly through a wide range of materials:
Metals: Stainless steel, cast iron, sheet metal, aluminum, copper, and alloy steel
Wood: Hardwood, softwood, and wood panels
Plastics: PVC and other rigid plastics
Laminated materials: Including laminated sheets and particle boards
This versatility makes it the all-in-one drilling solution for job sites, workshops, and home garages alike.
