Pointed chisel drill bit Makita B-64266 Length 400 mm

The Makita B-64266 pointed chisel drill bit Length 400 mm is a long-format masonry and concrete drill accessory designed for rotary hammer and SDS-plus compatible tools. With a 400 mm overall length and a pointed chisel tip, this drill bit is intended to deliver precise starting, controlled penetration and reliable performance when creating holes or channels in hard materials. The steel construction and optimized flute geometry support chip removal and extend service life under typical construction and renovation workloads.

Advantages

The pointed chisel tip improves centering and reduces wandering at the start of drilling, allowing for accurate hole placement without repeated pilot drilling. The extended 400 mm length enables reaching deeper anchors, through-holes and installations in thick walls or slabs. Robust material construction and a design suited for SDS-compatible hammer action contribute to consistent performance and reduced breakage risk during heavy-duty use.

Suitable for

• Drilling deep anchor and through-holes in concrete and masonry
• Creating channels and openings for plumbing, electrical and HVAC installations
• Renovation tasks where long-reach drilling is required
• Professional and DIY construction work using rotary hammer tools

Key specifications

• Overall length: 400 mm
• Tip type: pointed chisel
• Intended use: masonry, concrete and similar hard materials
• Compatibility: SDS-plus rotary hammer tools (SDS-type connection assumed by design)
• Construction: hardened steel body with spiral flute for chip evacuation

How to use

Secure the rotary hammer with the appropriate SDS-plus chuck and insert the pointed chisel drill bit fully into the tool retainer until it locks. Mark the drilling position on the work surface and use the hammer function at a steady, controlled feed rate to allow the tip to engage and cut efficiently. Apply consistent axial pressure without forcing the tool; allow the hammer action and drill geometry to remove material. Withdraw the bit periodically to clear dust and improve airflow for cooling and chip evacuation.

Usage recommendations

Use appropriate personal protective equipment including eye protection, dust mask and hearing protection when drilling masonry or concrete. For reinforced concrete, verify rebar locations and adjust technique to avoid prolonged contact with metal. Match drill speed and hammer settings to material density and replace the bit if wear degrades centering or cutting performance.
