Concrete Drill Bit Irwin Speedhammer Plus 6 x 460 mm PGM (10501959)

The Irwin Speedhammer Plus concrete drill bit 6 x 460 mm PGM is designed for drilling holes in concrete and masonry with SDS-plus rotary hammer drills. The 6 mm diameter and 460 mm overall length provide extended reach for through-drilling and deep anchor or conduit runs. The PGM tip geometry focuses impact energy and improves chip evacuation for consistent penetration in both reinforced and non-reinforced concrete.

Advantages

This drill bit combines a slim 6 mm profile with a long 460 mm working length to reach tight or deep positions without the need for extensions. The PGM tip geometry reduces walking at start-up and increases drilling speed, while the hardened flute and shank construction improve durability during repeated hammer drilling. Compatibility with SDS-plus chucks ensures secure retention and easy bit changes.

Suitable for

• Drilling anchor and dowel holes in concrete and masonry
• Running plumbing or electrical conduit through walls and slabs
• Sequential drilling tasks where multiple holes are required at fixed diameters
• Punching through light reinforced concrete and blockwork

Key specifications

• Diameter: 6 mm
• Overall length: 460 mm
• Tip geometry: PGM (optimized for rotary hammer impact and chip removal)
• Shank type: SDS-plus compatible
• Material: hardened steel with wear-resistant flute

How to use

Mount the bit securely in an SDS-plus rotary hammer chuck. For best results, start drilling at low speed to position the bit and then switch to hammer mode at the recommended drill setting. Apply steady axial pressure without forcing the bit; allow the hammer action and tip geometry to advance the hole. Remove accumulated dust periodically by retracting the bit or using a blow-out or vacuum system to maintain drilling speed and prevent overheating.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, hearing protection and dust mask. For reinforced concrete, use intermittent drilling and clear debris frequently. Match drill speed and hammer settings to the material hardness, and avoid twisting the shank when removing the bit to prolong tool life.
