Drill bit Irwin 10501969 twist drill bit 8 mm for rotary hammer 1 pc

Irwin twist drill bit model 10501969 is an 8 mm diameter drill designed for use with rotary hammer tools. Supplied as a single piece, this drill bit features a patented extra-short carbide tip and a single-flute geometry that together deliver faster penetration and efficient removal of drilling debris. The bit is brazed to withstand high temperatures during use and is shaped to fit SDS-compatible rotary hammers for common construction and DIY drilling tasks.

Advantages

The patented extra-short carbide tip places most of the cutting load in the head, improving durability and cutting speed. The tip is self-centering for better control and includes concave cutting angles that increase aggressiveness for faster drilling. A brazing process at high temperature ensures a strong bond between the tip and body, increasing heat resistance and tool life. The new single-flute design increases flute capacity for more effective dust clearance, reducing clogging and maintaining drilling efficiency. Overall design improvements deliver up to 20% faster drilling while preserving high durability.

Suitable for

• Drilling holes in masonry, concrete, and stone with rotary hammers
• General construction and renovation tasks requiring 8 mm holes
• DIY projects involving anchors, dowels, and fastener installation

Key specifications

• Drill diameter: 8 mm
• Tip: extra-short carbide tip with aggressive concave cutting angles
• Flute: single-flute design for improved waste removal
• Performance: up to 20% faster drilling compared with conventional designs
• Heat-resistant brazed tip for enhanced durability
• Shank compatibility: fits SDS-type rotary hammers

How to use

Install the drill bit into an SDS-compatible rotary hammer according to the tool manufacturer’s instructions, ensuring the shank locks securely. Select the rotary hammer’s appropriate mode and speed for masonry work. Position the bit at the required drilling point and start drilling with steady pressure; let the tool and the patented tip do the cutting. Periodically withdraw the bit to clear accumulated dust and allow cooling if drilling for extended periods. Replace the bit when signs of wear reduce cutting performance.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask when drilling. For best results, apply steady forward pressure without forcing the bit; allow the single-flute design to evacuate debris naturally. Match drill size to anchor or fastener specifications and avoid using the bit on materials for which it is not intended.
