Diamond crown bit AWTools 1036618 – 102 mm diameter, 430 mm length

Diamond crown bit AWTools 1036618 – 102 mm diameter, 430 mm length is a core drill bit designed for creating circular holes in hard substrates. The bit has a 102 mm cutting diameter and a total length of 430 mm, with a diamond-segmented cutting edge intended for effective coring in masonry, reinforced concrete and similar construction materials. It is designed for use with compatible rotary or core drilling rigs and accessories to produce accurate, clean holes for plumbing, electrical, HVAC and other installation needs.

Advantages

The diamond-segmented crown delivers high cutting efficiency and extended life when used on abrasive and dense materials. Its construction ensures stable rotation and consistent concentricity for precise hole sizes. The length provides sufficient reach for through-holes and deep installations while maintaining rigidity. The bit is suitable for use in wet or dry coring when paired with appropriate drilling equipment and cooling methods.

How to use

Mount the crown bit in a compatible drill or core rig using the correct adapter and secure it according to the machine manufacturer’s instructions. For best results, mark the hole position and start drilling at low speed to establish the guide, then increase speed and apply steady, even pressure. Use water cooling or periodic removal of debris when coring abrasive or reinforced materials to reduce heat and prolong cutting life. Follow safety procedures including eye protection, hearing protection and dust control.

Recommendations

Prefer wet coring when possible to extend diamond life and reduce dust; select drill speeds and pressure appropriate to material hardness and machine power. Inspect the crown segments and shank before each use and replace the bit if excessive wear or damage is present.
