## Summary description

Delphi Tools diamond core bit with 1 1/4" connection and 42/430 mm dimensions, designed for use with compatible core drilling machines. This diamond core bit is intended for drilling precise circular holes in hard materials; suitable for tasks in construction, plumbing and electrical installations where core extraction is required. Compatible with standard core drill mounts.

## Long description

Delphi Tools Diamond Core Bit 1 1/4" (42/430 mm) is a segmented diamond core bit designed for precision core drilling in hard materials. With a 1 1/4" connection and overall dimensions of 42/430 mm, this bit fits standard core drill mounts and is intended for creating clean, circular openings where extraction of a core is required. The construction balances cutting speed and life for typical on-site applications in construction, plumbing and electrical installation tasks.
Advantages
The segmented diamond rim provides efficient cutting through dense materials while maintaining durability. The standard 1 1/4" connection ensures compatibility with common core drilling machines and adapters. The bit's geometry is optimized to reduce vibration and improve straightness of the drilled hole, resulting in consistent core quality and easier core removal. Its design supports repeated use on abrasive and reinforced surfaces.
Suitable for
 Drilling circular openings in concrete and reinforced concrete
 Creating holes for plumbing installations and pipe penetrations
 Making precise feed-throughs for electrical conduits and cables
 Core extraction for inspection or sample-taking on construction sites
Key specifications
 Connection size: 1 1/4" (standard core drill mount)
 Overall diameter and length: 42/430 mm
 Cutting edge: segmented diamond rim for enhanced debris clearance
 Intended use: dry or wet core drilling depending on machine capability
 Material compatibility: concrete, reinforced concrete, masonry and similar hard substrates
How to use
Install the core bit on a compatible core drilling machine using the 1 1/4" connection and ensure it is securely tightened. When drilling, start at low speed to establish the pilot groove, then increase speed and apply steady, moderate feed pressure. Use water cooling if the machine and site conditions allow, to extend bit life and reduce dust; if water cannot be used, ensure frequent breaks to avoid overheating. After completing the hole, reverse the drill or use core extraction tools to remove the core sample safely.
Usage recommendations
For best results, match rotational speed and feed pressure to the substrate hardness, keep the bit centered at the start of drilling, and maintain proper cooling (wet drilling where possible). Inspect the bit for wear before use and replace when diamond segments are significantly worn to maintain hole quality and operator safety.
