Drill bit STHOR 23411, length 900 mm, single piece

STHOR 23411 drill bit, length 900 mm, single piece is an extended-length masonry/drilling accessory designed to reach deep or confined drilling points where standard bits are too short. Supplied as one piece with a long working shank, this drill bit is intended for applications that require significant reach such as drilling through thick walls, accessing recessed anchor points, or running services through partitions. It fits standard compatible drill chucks that accept long-shank bits and is suitable for professional and DIY tasks that call for reliable extended-reach performance.

Advantages

The long 900 mm length provides access to deep or hard-to-reach drilling locations without the need for multiple extensions or complex setups. Being a single-piece design reduces the risk of joint play or misalignment compared with multi-section extensions, ensuring straighter holes and consistent penetration. The bit is compatible with common drill chucks that accept long shanks, simplifying installation and use in a variety of construction and renovation environments.

Suitable for

• Drilling deep holes in masonry, concrete, or partition walls
• Installing anchors or sleeves in hard-to-reach locations
• Renovation and retrofit work where access is limited
• Electrical, plumbing, and HVAC penetrations through thick structures

Key specifications

• Length: 900 mm overall working length
• Supply format: single piece
• Compatibility: designed for use with drills accepting long-shank bits and standard chucks
• Application: extended-reach drilling for construction and installation tasks

How to use

Secure the drill in a compatible chuck that can accept the long shank, ensuring the bit is clamped firmly and aligned straight. Start drilling at low speed to establish a pilot track, then increase speed and apply steady pressure appropriate for the material being drilled. Withdraw the bit periodically to clear debris and reduce heat buildup. Maintain control of the extended-length tool to avoid flexing; using side handles or supports on the drill can improve stability during operation.

Usage recommendations

Use appropriate personal protective equipment, including eye and hearing protection and dust extraction when drilling masonry. Match drill speed and hammer action (if applicable) to the substrate and avoid excessive lateral forces that could bend the long bit. For best results in deep or reinforced concrete, consider step drilling and clearing debris frequently to prolong bit life and ensure accurate hole alignment.
