Drill bit Irwin Twist 7 mm 10501965 for rotary hammer 1 pc

Irwin Twist 7 mm drill bit (model 10501965) is designed for use with rotary hammers and offers a single-piece solution for creating precise 7 mm holes in common construction materials. The bit features a patented extra short carbide tip and a new single flute geometry that together improve drilling speed and waste removal. The shank is compatible with SDS rotary hammers, providing secure fitting and straightforward replacement when working with anchors, fasteners and mounting tasks.

Advantages

The patented extra short carbide tip concentrates up to 80% of the workload in the head to increase durability and drilling speed while the concave cutting angles provide more aggressive cutting action. A brazed carbide tip attached at high temperature ensures strong bonding and heat resistance for extended life. The unique single flute design has increased capacity for dust evacuation, reducing clogging and enabling more efficient drilling. Combined features deliver up to 20% faster drilling compared with conventional designs while maintaining high wear resistance.

Suitable for

• Drilling 7 mm holes for plastic or metal anchors in masonry and concrete
• Preparing fixing points for light to medium fixtures and fasteners
• Repair and installation work on construction sites or renovation projects
• Use with SDS-compatible rotary hammers for controlled, repeatable holes

Key specifications

• Diameter: 7 mm
• Tip: Carbide, extra short patented geometry
• Flute design: Single flute for increased waste removal capacity
• Drilling speed: Up to 20% faster due to tip and flute design
• Brazing: High-temperature brazed tip for improved heat resistance
• Shank type: SDS-compatible shank

How to use

Select a compatible SDS rotary hammer and secure the bit in the chuck according to the tool manufacturer’s instructions. Position the bit at the marked drilling point and start drilling with steady pressure, allowing the bit’s design to clear dust through the flute. For best results, begin at low speed to establish the hole and then use appropriate hammering action or speed for the material being drilled. Withdraw periodically to clear debris if drilling deep holes.

Usage recommendations

Use the drill bit with a rotary hammer that supports SDS shanks and select suitable protective equipment such as eye and hearing protection. For anchor and fastener installation, verify the substrate and anchor type before drilling and follow recommended drilling depths and cleaning procedures for secure fixation.
