Drill bit Irwin SDS+ 12 mm model IW2039422 for concrete

The Irwin SDS+ 12 mm drill bit model IW2039422 is designed for percussive drilling in concrete, brick and other masonry materials. It features an SDS+ shank that fits compatible rotary hammer drills and a 12 mm diameter suitable for medium-duty anchoring, conduit routing and fixture installation. The tip geometry is optimized for impact drilling to provide stable drilling progress in hard substrates while maintaining hole accuracy.

Advantages

This SDS+ 12 mm drill bit offers reliable compatibility with SDS+ hammer drills, a durable tip shape engineered for percussion action, and a diameter that balances hole size and drilling speed for common concrete tasks. The bit is intended to deliver consistent hole dimensions and predictable performance when used with appropriate drilling modes and speed settings.

Suitable for

• Drilling anchor holes for bolts and mechanical fixings in concrete and masonry
• Creating passages for electrical conduits and plumbing sleeves through walls
• Installing fixtures such as brackets, railings and anchors in brick or blockwork
• Medium-duty repair and renovation tasks involving masonry penetration

Key specifications

• Shank type: SDS+ for use with compatible hammer/rotary hammers
• Diameter: 12 mm suitable for medium-size anchor and conduit holes
• Intended material: concrete, brick and general masonry
• Tip geometry: designed for percussive drilling performance and centering stability

How to use

Secure the SDS+ 12 mm drill bit into the chuck of a compatible rotary hammer so the shank locks firmly. Select the hammer drilling mode and an appropriate rotational speed for the substrate. Mark the drilling point, start at low speed to establish the position, then apply steady axial pressure while allowing the hammer action to advance the hole. Periodically withdraw the bit to clear debris and prevent clogging in deep holes. Use suitable personal protective equipment and ensure the workpiece is stable before drilling.

Usage recommendations

For best results, match drill speed and hammer setting to the hardness of the material, use lubrication or cooling only when recommended by the tool manufacturer, and replace the bit when wear affects drilling accuracy or penetration rate. When installing anchors, verify hole depth and diameter against anchor specifications before insertion.
