Vacuum Brazed Dry Diamond Drill M14 with 50mm working length

M14 fitment for direct connection to 115mm or 125mm angle grinders. Designed to operate dry at speeds in excess of 10,000rpm.

16mm upwards have a 50mm working length 20mm more than standard Vacuum Brazed Holesaws

Suitable for cutting any hard material including Ceramic, Porcelain, Marble, Granite, man made Quartz, Engineered stone, Concrete or Brick. In fact these Diamond Holesaws will drill pretty much anything you can throw at them, however their lifespan in very dense materials such as porcelain or granite can be reduced.

If you’re looking specifically for diamond drill bits for cutting multiple holes in Granite then it’s likely our Sintered Dry Gold Holesaw will be a more suitable long term solution.

If you’re looking for a solution for 6,7 & 8mm holes specifically for porcelain tiles we recommend the wax filled drill bits or Glass and Hard Porcelain bits if you’ve got a real problem tile, over these M14 drills.

An M14 to Hex adapter is available to convert these bits for use in standard drill chucks, making the bits dual use. However if you do want to use these on a drill they are better run at full speed on a corded drill, cordless battery drills tend to run to slow and they will likely reduce the lifespan of the bit and the speed at which the holes are drilled.
