About this item

• Precision Ground Edges: Every twist bit is fully ground for sharp honed cutting edges; 135 degree split point self-centers without a pilot hole; creates clean burr-free holes with minimal chatter
• High Concentricity Hex Shank: Precision-machined 1/4 inch hex shank locks into quick-change chucks and any impact driver; eliminates radial runout and wobble; keeps bits straight during continuous use
• Titanium HSS Build: High-grade HSS substrate with uniform titanium coating; two spiral flutes clear chips fast to reduce friction. heat; hardened honed edges stay sharp through repeated workshop use
• Versatile Material Compatibility: Drills mild steel. carbon steel. sheet metal. solid wood and plastics; titanium coated bits suit home repairs. DIY. workshop and engineering tasks with most power tools
• Complete Metric Size Set: 19 pieces in 13 metric sizes from 1.5 mm to 6.5 mm matching 1/16 inch to 1/4 inch; six common sizes include a backup piece each; each shank is size-marked for quick identification

This 19 piece hex shank twist drill bit set delivers consistent accuracy for daily drilling and light work. built for power tool users and DIY enthusiasts. Made from high grade high speed steel with a titanium coating for reliable repeated performance in home repair and workshop environments.

Precision Engineering Design
Every bit is fully ground for sharp edges and tight concentricity. The 135 degree split point self-centers to prevent walking; the titanium coating reduces friction and heat buildup. preserving sharpness and service life. Two spiral flutes clear chips quickly. keeping cuts cool when drilling wood or plastic.

Quick Change Convenience
The universal 1/4 inch hex shank locks into most power drills. impact drivers and quick-change chucks for fast bit swaps between drilling and driving with one tool. The hex head design offers quick connect speed for frequent bit changes.

Full Set Contents
1. 19 pieces covering 13 metric sizes from 1.5 mm to 6.5 mm. including small diameters matching 1/16 inch to 1/4 inch
2. Six commonly used diameters include two backup pieces each for uninterrupted work
3. Each hex shank is clearly marked with its size for fast identification on the job

Tool and Material Compatibility
The set performs reliably on mild steel. carbon steel. sheet metal. solid wood and general plastics. Uses include pilot holes for screws. assembly. home repair and engineering tasks. A practical drill bit kit for power tool use. This set is not designed for hardened steel. stainless steel. glass. ceramic. concrete or masonry.

Operation Guidelines
For best results. match drill speed to the material and apply steady. moderate pressure. Clear chips regularly and avoid prolonged dry drilling to prevent premature dulling. Use lower speeds for metal. higher speeds for wood or plastic. Cutting fluid for metal work improves hole quality and extends bit life.
