Drill bit 920 mm, 14 Degrees East DT60836 is a long, single-piece masonry drill designed for deep drilling tasks where extended reach is required. Compatible with chucks and holders that accept long-diameter bits, this 920 mm length is intended for use in reinforced concrete, masonry, natural and artificial stone. The bit features a solid carbide tip with four cutting faces for reduced jamming in rebar, improved hole concentricity and consistently high drilling speeds. A long helix and optimized flute geometry promote fast debris evacuation, while heat-treated construction increases overall strength and durability for professional jobsite use.
Advantages
The solid carbide tip with four cutting faces minimizes the risk of jamming when encountering rebar and delivers cleaner, more concentric holes. The extended 920 mm length provides substantial reach for through-wall and deep-beam drilling applications. Optimized helix geometry and increased free space in the flute enable faster removal of dust and chips, reducing packing and maintaining drilling performance. Heat treatment of the shank and flutes enhances strength and resistance to wear under heavy loads.
Suitable for
- Drilling through reinforced concrete and masonry where long reach is needed
- Creating holes in natural and artificial stone
- Installations requiring deep anchor or conduit holes through thick walls and beams
- Tradespeople and installers working on renovation or construction sites
Key specifications
- Overall length: 920 mm
- Tip: solid carbide with four cutting faces
- Material compatibility: reinforced concrete, masonry, natural and artificial stone
- Helix: long helix with optimized flute geometry for debris removal
- Construction: heat-treated shaft and flute areas for increased strength
- Supply: single piece
How to use
Select a compatible drill or holder that supports long masonry bits and clamp the bit securely. Start drilling at low speed to establish the hole position, then increase speed and feed pressure appropriate for the substrate. Use intermittent withdrawal to clear accumulated debris if drilling deep holes, and maintain consistent alignment to ensure concentric holes. For extended drilling sessions, allow the bit to cool periodically or use recommended drilling aids to manage heat and dust.
Usage recommendations
Use suitable personal protective equipment, dust extraction or wet drilling where applicable, and ensure the drill and chuck are rated for long, heavy bits. Inspect the carbide tip for wear before use and replace the bit when cutting performance declines to maintain efficient and safe drilling.
