Drill Bit Smart SDS‑MAX 38 mm for Concrete, model 18-380320

Drill Bit Smart SDS‑MAX 38 mm for Concrete, model 18-380320 is a rotary-hammer bit designed for drilling through-holes and anchor holes in concrete, masonry and reinforced concrete. The bit features an SDS‑MAX shank for secure fitting in compatible rotary hammers. It is intended for professional construction and renovation tasks requiring a 38 mm bore and a tool that maintains stability during percussive drilling.

Advantages

The SDS‑MAX 38 mm concrete bit provides a stable shank engagement and reliable transfer of impact energy from rotary hammers to the cutting head. Its diameter and geometry are optimized for creating clean through-holes and anchor holes in dense materials, while the robust construction resists wear under frequent use. Compatibility with SDS‑MAX tool interfaces ensures consistent centring and reduced play during drilling operations.

Suitable for

• Drilling through-holes in concrete for anchors and sleeves
• Making anchor holes in reinforced concrete and masonry
• Preparation of service penetrations for plumbing and electrical conduits
• Professional construction and renovation where a 38 mm bore is required

Key specifications

• Shank type: SDS‑MAX for use with compatible rotary hammers
• Nominal diameter: 38 mm suitable for 38 mm anchors and sleeves
• Intended material: concrete, reinforced concrete and masonry
• Primary function: through-holes and anchor holes
• Design focus: stable fit and efficient impact transfer

How to use

Install the SDS‑MAX shank into a compatible rotary hammer according to the tool manufacturer's instructions until it locks securely. Position the bit perpendicular to the drilling surface and start at low feed pressure to establish a pilot contact point, then apply steady axial pressure while operating the hammer function. Use water flushing or a vacuum extraction system if required to remove dust and debris and to maintain visibility in the hole. Withdraw the bit periodically on deep holes to clear cuttings and avoid overheating.

Usage recommendations

For best results, use the drill bit with rotary hammers specified for SDS‑MAX bits and within their recommended impact energy range. Wear appropriate personal protective equipment, use dust extraction when working indoors, and select the correct drilling mode (rotary hammer) rather than rotary-only mode. Inspect the bit regularly for wear or damage and replace it if the cutting head shows significant deterioration.
