Diamond crown drill bit Flex RM-TX 1 1/4" (62 mm) x 450 mm, dry cutting

Diamond crown drill bit Flex RM-TX 1 1/4" (62 mm) x 450 mm is a dry cutting core bit designed for creating clean, precise holes with a 62 mm diameter and 450 mm overall length. Manufactured by Flex, this drill bit is intended for dry drilling in masonry, concrete and similar hard substrates. It fits machines that accept a 1 1/4" connection and is suitable for tradespeople who need to cut or core through tough materials without water cooling.

Advantages

This diamond crown drill bit provides high cutting efficiency on dense materials thanks to its diamond-segmented rim and robust construction. The 62 mm diameter offers a standardized hole size for installations while the 450 mm length allows for deeper penetration and through-holes in many common wall and floor thicknesses. Designed for dry cutting, it eliminates the need for water supply and simplifies on-site setup. Compatibility with 1 1/4" tool connections ensures stable mounting and reliable torque transfer during core drilling.

How to use

Secure the Flex RM-TX diamond crown bit in a compatible core drill or rotary hammer with a 1 1/4" connection. Mark the drilling position and ensure the workpiece is stable. Start drilling at low speed to establish a guide groove, then increase speed and apply steady axial pressure, allowing the diamond segments to cut without forcing. Monitor progress and periodically withdraw the bit to clear dust from the core and segments. Because this bit is intended for dry cutting, ensure adequate dust extraction and personal protective equipment are used to control dust and protect the operator.

Usage recommendations

For best results, use appropriate drill speeds recommended by the tool manufacturer, maintain steady pressure without excessive side loading, and employ a dust extractor or vacuum system when working in enclosed spaces to reduce airborne dust. Allow the bit to cool between extended runs if heavy duty work generates high temperatures.
