Rotary hammer accessory STHOR 23591 — length 250 mm, diameter 14 mm, 1 pc

STHOR 23591 rotary hammer accessory, length 250 mm and diameter 14 mm, is a single-piece replacement bit designed for use with compatible rotary hammers and SDS systems. It is intended for drilling and light chiseling tasks in construction, renovation and general masonry work where a 14 mm tool diameter is required. The steel construction delivers the rigidity needed for repetitive impact drilling in concrete, brick and other common building materials.

Advantages

The 250 mm length provides extended reach for deeper holes while maintaining control and stability. A 14 mm diameter offers a balance between hole size and tool strength suitable for many anchoring and fastening applications. Supplied as one piece, the bit is ready for immediate replacement of worn or damaged accessories, reducing downtime. Compatibility with standard SDS-style rotary hammers ensures straightforward installation and reliable retention in the tool chuck.

Suitable for

• Drilling holes for anchors and fasteners in concrete and masonry
• Through-drilling in brick and block walls where 250 mm depth is needed
• Renovation and construction tasks requiring a 14 mm bore
• Replacing worn SDS accessories on compatible rotary hammers

Key specifications

• Length: 250 mm
• Diameter: 14 mm
• Quantity: 1 piece
• Tool connection: SDS-compatible shank
• Primary materials: hardened steel for impact drilling

How to use

Install the accessory in the rotary hammer’s SDS-style chuck ensuring it locks securely before operation. Use the appropriate rotation and hammer settings on the tool for drilling into concrete, brick or block. Apply steady axial pressure without forcing the bit; allow the hammer action to provide the cutting and impact. Withdraw the bit periodically when drilling deep holes to clear dust and debris and to prevent overheating and excessive wear.

Usage recommendations

For best results, use appropriate personal protective equipment (safety glasses, gloves and hearing protection) and select drill speed and hammering intensity according to the base material. Replace the accessory if signs of excessive wear, bending, or chipping appear to maintain drilling accuracy and user safety.
