Drill bit STHOR 23390, solid shaft, length 600 mm, 1 pc

The STHOR 23390 drill bit is a single-piece, solid-shaft tool with a length of 600 mm designed for drilling tasks that require extended reach. Supplied as one piece per pack, this long masonry/concrete-capable bit is built to work with compatible rotary and hammer drills for construction, renovation and maintenance jobs where a longer drill length is necessary.

Advantages

This solid-shaft 600 mm drill bit provides increased reach for deep or hard-to-access holes while maintaining the rigidity needed for controlled drilling. Its single-piece construction reduces the risk of shaft play or separation under load. The design is suitable for use in drills that support long bits and helps maintain stability and straightness during penetration into masonry and concrete surfaces.

Suitable for

• Drilling deep holes in concrete and masonry
• Installation of anchors and fixings in walls and foundations
• Repair and renovation work requiring extended bit length
• General heavy-duty drilling where long reach is required

Key specifications

• Type: solid-shaft, single-piece drill bit
• Length: 600 mm
• Quantity: 1 piece per pack
• Intended materials: concrete, masonry, and similar mineral substrates (performance depends on drill and material)
• Compatibility: for use with drills that accept long masonry/concrete bits (rotary and hammer drills dependent on chuck and mode)

How to use

Secure the drill bit firmly in the drill chuck, ensuring the shank is fully inserted and tightened according to the drill manufacturer's instructions. Select the appropriate drilling mode (rotary or hammer) based on the drill and the material. Start drilling at low speed to establish the pilot and then apply steady pressure, increasing speed as appropriate. Periodically withdraw the bit to remove dust and debris and to prevent overheating. Use appropriate personal protective equipment such as eye protection, gloves and dust mask when drilling.

Usage recommendations

For best results, match the drill and drilling mode to the material: use hammer mode for hard concrete and rotary mode for softer masonry where appropriate. Avoid excessive lateral force to maintain bit straightness. If drilling deep holes, clear debris frequently and allow intermittent cooling to prolong bit life.
