Diamond core bit AWTools 1 1/4 inch (32 mm) 72/430 mm, model 1036604

AWTools diamond core bit 1 1/4" (32 mm) 72/430 mm, model 1036604, is a precision core drill designed for creating through-holes and extracting core samples in concrete, masonry and other hard mineral materials. The tool incorporates industrial-grade diamond cutting segments mounted on a steel body to provide consistent cutting performance and extended service life when used with compatible rotary drills or drill rigs. Its 32 mm cutting diameter and 72/430 mm overall geometry make it suitable for tasks that require accurate, straight cores and reliable chip removal.

Advantages

The diamond segments deliver efficient material removal and maintain cutting sharpness over prolonged use, which reduces the need for frequent replacements. A robust steel core construction offers dimensional stability and resistance to bending during drilling operations. The bit’s dimensions are optimized to balance cutting speed and core integrity, while compatibility with standard rotary and rig-mounted systems simplifies integration into existing tool fleets. Overall, the design focuses on predictable performance in demanding drilling conditions.

How to use

Select a compatible drill or drill rig with the correct mounting interface and sufficient power for the intended material. Secure the workpiece or ensure stable positioning before starting. Begin drilling at low speed to establish the cutting line, then increase speed and apply consistent axial pressure while allowing the diamond segments to cut without excessive force. Use water cooling or periodic withdrawal to clear debris and control temperature when drilling in dense or abrasive materials. After completing the hole or extracting the core, stop the drill and allow the bit to cool before handling or storing.

Recommendations

For best results, match drill speed and feed rate to the hardness of the material, use continuous water cooling for reinforced concrete or prolonged drilling, and inspect the bit periodically for segment wear. Replace the core bit if excessive vibration or loss of cutting efficiency occurs to maintain hole quality and operator safety.
