Drill bit Irwin 10501946 twist 5 mm for rotary hammer 1 pc

Irwin twist drill bit 10501946 is a 5 mm diameter drilling accessory designed for use with SDS-compatible rotary hammers. Supplied as a single piece, this bit features a patented extra-short carbide tip and a new single flute design that together improve drilling speed and waste removal. The brazed carbide tip and shank shaped for SDS rotary hammer fitting make the bit suitable for standard drilling tasks in a range of materials when used with an appropriate rotary hammer.

Advantages

The patented extra-short carbide tip carries most of the cutting load, providing higher durability and faster penetration while the concave cutting angles make drilling more aggressive. A brazing process at high temperature ensures a strong bond between tip and body for extended life. The new single flute increases waste removal capacity and reduces clogging by clearing drilling dust directly into the flute. Overall design improvements deliver up to 20% faster drilling speed while maintaining durability, and the self-centering tip facilitates easier control.

Suitable for

• Standard drilling tasks requiring a 5 mm hole
• Drilling in metal and wood where rotary hammer compatibility is available
• General-purpose workshop and on-site drilling with SDS rotary hammers

Key specifications

How to use

Install the 5 mm Irwin twist bit into an SDS-compatible rotary hammer according to the tool manufacturer's instructions, ensuring the shank is fully engaged and locked. Select an appropriate speed and hammer setting for the material being drilled. Start drilling with moderate pressure and allow the patented tip and single flute to remove debris; avoid excessive force to prevent overheating. Withdraw the bit periodically in deeper holes to clear chips and check progress. After use, clean debris from the flute and store the bit in a dry place.

Usage recommendations

Use appropriate personal protective equipment (safety goggles, gloves, hearing protection) and follow the rotary hammer manufacturer's safety guidelines. For best results, match drill speed and hammer action to the material; reduce speed and use steady pressure for metal and increase hammer action for masonry where applicable. Regularly clear chips from the flute to maintain drilling efficiency and prolong bit life.
