Drill Bit Makita P-59938 14 x 600 mm for Concrete, SDS-plus

Makita P-59938 14 x 600 mm SDS-plus concrete drill bit is engineered for deep-hole drilling in concrete and masonry. The 14 mm diameter and 600 mm length enable drilling for anchor installation, through holes for conduit and pipes, and deep structural penetrations. The bit features a hardened carbide tip and optimized flute geometry to remove dust and debris efficiently and to maintain consistent drilling performance when used with SDS-plus rotary hammers.

Advantages

This drill bit offers long-reach capability with stable centering and reduced walking on start-up thanks to its precise tip design. The hardened carbide tip improves wear resistance on abrasive concrete and masonry, while the flute profile accelerates chip extraction, reducing clogging and heat build-up. Compatibility with SDS-plus chucks provides secure attachment and reliable power transfer for rotary hammer drilling applications.

Suitable for

• Drilling deep holes in concrete for anchors and heavy-duty fixings
• Creating through-holes for electrical conduits and plumbing runs
• Structural and renovation works that require long-reach drilling
• Professional and trade use with SDS-plus rotary hammers

Key specifications

• Diameter: 14 mm
• Overall length: 600 mm
• Shank type: SDS-plus compatible
• Tip material: hardened carbide
• Intended material: concrete and masonry

How to use

Fit the drill bit into the SDS-plus chuck of a compatible rotary hammer until it locks securely. Select hammer mode and appropriate drill speed on the tool, align the bit with the intended drilling point and apply steady forward pressure without forcing. Withdraw periodically to clear debris on long holes, and allow the bit and tool to cool during extended use. Replace the bit when tip wear reduces drilling efficiency or size accuracy.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and respiratory protection when drilling concrete. For precise anchor holes, pre-mark and use a guide or pilot hole where possible. Inspect the bit for damage before use and store in a dry place to prevent corrosion.
