## Summary description

## Long description

Makita D-44541 is a 45 mm diamond core drill bit with an M14 threaded connection, engineered for coring hard surfaces. It is designed to cut precise circular holes in materials such as granite, marble and ceramic tile. The diamond-segment cutting edge and robust steel body provide controlled cutting performance for wet or dry coring when used with a compatible rotary hammer or core drill. Typical applications include openings for plumbing, electrical fittings and finishing work in tiled or stone surfaces.
Advantages
This 45 mm diamond core drill bit offers durable diamond cutting segments that maintain sharpness for extended service life under recommended conditions. The M14 threaded connection ensures compatibility with a wide range of hand-held and bench-mounted coring attachments that accept this thread. The design supports both wet and dry coring, allowing flexible use depending on the jobsite and material, while the segmented edge helps produce clean, round holes with minimal chipping on finished stone and tile.
Suitable for
 Coring holes in granite and marble for plumbing and fixture installations
 Cutting clean openings in ceramic and porcelain tile for anchors and pipes
 Creating precise circular holes in countertops, facades and floor tiles
When it may not be suitable
This diamond core drill bit is optimized for hard natural stone and ceramic surfaces; it may deliver reduced performance or accelerated wear if used primarily on highly abrasive concrete mixes with large aggregates or on soft, fibrous materials. For very large-diameter cores, specialized core barrels or different product families may be more appropriate.
Key specifications
 Cutting diameter: 45 mm
 Connection thread: M14
 Cutting type: diamond-segment core bit
 Recommended use: wet or dry coring
 Primary materials: granite, marble, ceramic tile
How to use
Mount the diamond core bit onto a compatible tool with an M14 threaded spindle, ensuring it is securely tightened. When coring, start at low speed to establish the hole, then apply steady pressure and maintain constant rotation. For tiled or polished stone surfaces, consider starting at an angle to prevent slipping, then gradually straighten the drill. Use water cooling when possible to extend bit life and reduce dust; when dry coring, follow the tool manufacturer's recommendations for cooling intervals to avoid overheating. Keep the workpiece stable and wear appropriate personal protective equipment.
What to consider before purchase
 Confirm your drill or adapter accepts an M14 threaded bit
 Verify the 45 mm diameter meets the required hole size for fixtures or pipes
 Decide whether wet coring is available on site to maximise bit life
Usage recommendations
For best results on granite and marble, use steady low-to-moderate feed pressure, prefer wet coring when possible, and periodically withdraw the bit to remove slurry. On ceramic tile, start at a shallow angle and use masking tape over the cut point to reduce chipping.
