Rotary hammer accessory STHOR 23593 — drill/bit length 250 mm, diameter 14 mm, 1 pc

STHOR 23593 is a rotary hammer accessory — a single 14 mm diameter drill/bit with a length of 250 mm designed for use with compatible rotary hammers. Supplied as one piece, this bit is intended as a replacement or spare for drilling in concrete, masonry and similar building materials where a 14 mm hole is required. The design focuses on straightforward interchangeability with tools that accept standard SDS-plus or compatible chucks (check your tool compatibility before use).

Advantages

This 250 mm long, 14 mm diameter bit provides sufficient working length for through-holes and deeper drilling tasks while keeping a compact profile for handling. As a single-piece spare, it simplifies inventory and replacement needs on site. The bit is suitable for repeated use in construction and renovation environments when matched to a compatible rotary hammer. Its length and diameter combination offers a balance between reach and rigidity for controlled drilling in masonry and concrete.

Suitable for

• Drilling 14 mm holes in concrete and masonry
• Replacement spare for compatible rotary hammers
• Renovation and repair work requiring medium-depth holes
• Installation of anchors, dowels or conduit passages

Key specifications

• Drill/bit diameter: 14 mm
• Overall length: 250 mm
• Quantity in pack: 1 piece
• Intended material use: concrete, masonry and similar substrates
• Compatibility: for rotary hammers that accept the corresponding shank type (verify tool chuck type)

How to use

Install the bit into a compatible rotary hammer according to the tool manufacturer's instructions and secure it in the chuck. Mark the drilling point, use appropriate personal protective equipment (safety glasses, gloves, hearing protection) and select a suitable drilling speed and impact setting for concrete or masonry. Apply steady axial pressure and allow the tool to advance the bit without excessive force. Withdraw the bit periodically to clear dust and debris for efficient cutting. After use, clean the bit and store it dry to prevent premature wear.

Usage recommendations

Verify the shank type and compatibility with your rotary hammer before use. For best results in reinforced concrete or very hard substrates, consider using a carbide-tipped drill and adjust impact settings as recommended by the rotary hammer manufacturer. Replace the bit when wear reduces drilling efficiency or when the cutting edges are visibly damaged.
