Distar DISTAR DIAMOND CROWN RM-TX 1 1/4" 112mm x 300mm DRY Diamond Core Drill Bit

The Distar DISTAR DIAMOND CROWN RM-TX 1 1/4" 112mm x 300mm DRY Diamond Core Drill Bit is a professional power tool accessory engineered for efficient and clean dry core drilling operations. Built to handle demanding construction and renovation environments, this diamond core drill bit delivers reliable performance in hard building materials without the need for water cooling. Featuring standard physical dimensions and a robust build, it integrates seamlessly with compatible core drilling equipment to ensure precise hole creation.

Advantages

This dry diamond core drill bit provides high cutting efficiency and clean hole edges, reducing the need for secondary material finishing. Its specialized diamond segment design allows for stable operation during intensive dry drilling tasks, minimizing downtime and increasing productivity on the job site. The robust construction ensures extended tool longevity even when working with challenging construction surfaces.

Suitable for

• Dry core drilling in professional construction and renovation projects
• Creating precise openings for utility pipes and ventilation systems
• Working with hard building materials where water supply is unavailable

When it may not be suitable

This product is not recommended for wet drilling applications or for use with low-power handheld drills that lack the torque required for large-diameter core bits. It is also unsuitable for drilling through soft or abrasive materials that require specialized segment bonds.

Key specifications

• Core drill bit type: Diamond dry core drill bit
• Connection thread: 1 1/4"
• Diameter: 112 mm
• Working length: 300 mm
• Drilling method: Dry

How to use

Mount the diamond core drill bit securely onto a compatible core drilling machine using the 1 1/4" connection thread. Ensure the equipment is switched off and unplugged during installation. Align the drill bit perpendicular to the surface and initiate drilling at the recommended speed for dry applications. Apply steady, moderate pressure without forcing the tool, allowing the diamond segments to cut through the material efficiently while periodically clearing dust from the hole.

What to consider before purchase

• Verify that your drilling equipment features a 1 1/4" connection thread
• Ensure your drill has sufficient power and stability for a 112 mm diameter bit
• Confirm that your project requirements align with dry drilling methods

Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses, respiratory protection, and hearing protection, when operating dry core drills. Inspect the diamond segments for wear before each use and avoid lateral pressure during drilling to prevent segment damage.
