Applications

Perfect for metalworking workshops, automotive repair, construction, and machinery manufacturing. The 14mm diameter and reduced shank design make it versatile for use with standard drill presses and handheld drills, delivering consistent results in industrial-grade materials.

Performance Advantages

The notched chisel point geometry reduces drill walking during startup, while the 30o helix efficiently clears chips to prevent clogging. HSS construction ensures resistance to wear, and the dual-finish treatment balances heat management with shank durability, extending tool life in high-volume operations.

Quality Assurance

Manufactured to strict industrial standards, each drill bit undergoes precision grinding and thermal treatment. The steam tempering process creates a porous surface that enhances lubrication, while post-grinding ensures sharp cutting edges and dimensional accuracy.

Differentiation

Unlike standard drill bits, our reduced shank design combines 14mm cutting capacity with 1/2″ shank compatibility, eliminating the need for adapter sleeves. The notched point variation offers superior starting control compared to conventional chisel points, reducing material waste and rework.
