Drill Bit Makita P-23721

The Makita P-23721 drill bit is designed for use with rotary hammers and features an SDS Max shank for a secure mechanical connection. At 400 mm overall length, this single carbide-tipped bit is intended for deeper drilling tasks in concrete, masonry and similar substrates. The bit is produced to meet professional jobsite demands for consistent performance and wear resistance.

Advantages

This drill bit provides reliable engagement with SDS Max chucks and sustained cutting performance over extended drilling operations. Its 400 mm length enables deep-hole drilling without the need for extension, while the carbide tip and hardened body improve lifespan under repeated impact and rotation. The single-piece design reduces wobble and assists in maintaining a straight bore during demanding applications.

Suitable for

• Drilling deep holes in concrete and reinforced concrete
• Anchoring and through-hole installations in masonry
• Professional construction and renovation tasks requiring rotary hammers
• Installation of sleeves, dowels and heavy-duty fixings

Key specifications

• Shank type: SDS Max for rotary hammer tools
• Overall length: 400 mm suitable for deep drilling
• Tip material: carbide-tipped for improved wear resistance
• Intended materials: concrete, masonry and similar substrates
• Design: single-piece bit for reduced runout and stable drilling

How to use

Mount the drill bit into the rotary hammer’s SDS Max chuck following the tool manufacturer’s instructions until it locks securely. Select an appropriate rotary hammer mode (hammer drilling) and a suitable drilling speed according to the substrate. Apply steady axial pressure without forcing the bit to allow the hammer action and carbide tip to cut efficiently. Withdraw occasionally to clear dust and debris from the hole when drilling deep to maintain cutting efficiency and reduce heat build-up.

Usage recommendations

Use appropriate personal protective equipment, including eye and hearing protection, and follow the rotary hammer manufacturer’s safety guidelines. For reinforced concrete, start with a pilot hole if required and consider core cooling/cleaning intervals for prolonged drilling. Store the bit in a dry place to prevent corrosion and inspect the tip for wear before critical tasks.
