Drill bit STHOR 23421, length 900 mm, single piece

STHOR 23421 drill bit, 900 mm length, single piece, is designed for making deep holes where extended reach is required. The bit follows common shank geometry to fit standard drill chucks and rotary equipment used in construction and installation. It is intended for drilling deep anchor holes, starting deep cores, or reaching recessed fixing points in compatible materials such as masonry and similar substrates.

Advantages

The 900 mm length provides extended reach for drilling tasks that standard bits cannot accomplish, reducing the need for extensions or repeated repositioning. Delivered as a single solid piece, the drill bit ensures consistent alignment and rigidity during use. Its shank geometry matches common chucks, enabling straightforward mounting in a range of drill drivers and rotary tools suitable for masonry work.

Suitable for

• Drilling deep anchor holes in masonry
• Starting deep cores or long through-holes
• Reaching recessed fixing points in walls or structures
• Installation tasks requiring extended drill reach

Key specifications

• Overall length: 900 mm
• Packaging: single piece
• Shank type: standard shank geometry compatible with common drill chucks
• Intended materials: masonry and similar construction substrates
• Primary use: deep drilling and extended-reach applications

How to use

Select a drill or rotary tool with a chuck that accepts the bit's shank geometry and ensure the machine has sufficient power and speed settings for masonry drilling. Mark the drilling point and secure the work area. Mount the bit firmly in the chuck, set the appropriate hammer or rotary mode if applicable, and start drilling using steady, moderate pressure. Withdraw the bit occasionally to clear debris and prevent binding. After completion, clean the bit and store it dry to maintain condition.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, gloves, and hearing protection. For hard or reinforced substrates, verify tool power and consider pre-drilling pilot points if needed. Avoid excessive lateral force to prevent bending; when encountering dense material, withdraw to clear dust and allow the bit to cool.
