Drill bit set DeWALT DT4956-QZ 6 pc(s)

The DeWALT DT4956-QZ 6 pc drill bit set is designed for drilling high-alloy steels and other metals with tensile strength up to 1100 N/mm². The set contains six precision-engineered bits that combine a no-walk tip for straightforward penetration with recessed cutting wings to produce cleaner, more accurate, and burr-free holes. Each bit has a three-sided, spin‑proof shaft for reliable grip in the drill chuck, suitable for both portable and stationary drilling.

Advantages

Bits are made for high-alloy steels and metals up to 1100 N/mm², offering improved penetration through the no-walk tip and reduced wandering on the workpiece. Recessed cutting wings reduce burr formation and improve hole finish while the three-sided shank prevents slippage in the chuck for consistent torque transfer and accurate drilling.

Suitable for

• Portable drilling of high-alloy steel and metal
• Stationary (bench or pillar) drilling of steel and metal
• Creating clean, burr-free holes in materials with tensile strength up to 1100 N/mm²
• Applications requiring a slip-resistant shank for secure chuck grip

Key specifications

• Brand: DeWALT
• Model / MPN: DT4956-QZ
• Quantity: 6 pieces
• Suitable material: High-alloy steels and metals up to 1100 N/mm² tensile strength
• Tip type: No-walk (self-centering) tip
• Shank: Three-sided spin-proof shank (no-slip)

How to use

Select the appropriate bit size from the set for the required hole diameter. Secure the bit in the drill chuck, ensuring the three-sided shank seats firmly to prevent slipping. Use steady, moderate feed pressure and suitable cutting speed for the metal being drilled. For portable drilling, stabilize the workpiece and maintain perpendicular alignment. For stationary drilling, clamp the workpiece and follow normal drill-press procedures. Withdraw the bit periodically to clear chips and avoid overheating.

Usage recommendations

For best results, use appropriate cutting fluid when drilling hardened or high-alloy steels, maintain correct drilling speeds, and allow the bit to cool between passes to prolong tool life and preserve hole quality.
