Anti-Slip Hex Shank

One-Piece Design

Quick Change

The solid hex shank high-speed steel twist drill bits are designed with an integrated structure. The drill body and hex shank are formed as a single unit, they are processed and manufactured by one-piece bar. Compared to common welded or assembled structures, this design offers superior concentricity and overall strength, ensuring greater stability and reliability during actual drilling operations. The hex shank design effectively prevents slippage, guaranteeing a secure grip in chucks, making it particularly suitable for common power tools such as quick-change chucks and electric drills.

Manufactured from premium high-speed steel and subjected to optimized heat treatment, this product balances hardness with toughness. It is suitable for drilling common metals including mild steel, thin steel plates, aluminum, and other standard materials. The one-piece construction minimizes energy loss during torque transmission, enhancing drilling efficiency and reducing breakage risk.

The hexagonal shank design enables rapid clamping and replacement, boosting operational efficiency. It is particularly suitable for assembly, installation, high sky work, and routine industrial applications. The product's structural design balances stability and practicality, making it ideal for continuous operation environments requiring basic drilling precision and reliability.

This solid hex shank twist drill is primarily recommended for rotary tools like electric drills. It maintains stable performance under light-load drilling conditions, serving as a standard industrial drilling tool that balances versatility and practicality.
