Inland Grinding Bits


All Inland grinder bits are plated in our ISO9001:2000 facility in Michigan. Because we plate our own diamond products we can offer the absolute best drums at better prices than anyone else. The diamond coating on your Inland drum will never peel from the drum or we'll replace it for free for the life of the diamonds. You will never need to knock off the "bunchings" on an Inland bit--we don't call them "bunchings', we call them "defects" and our Quality Control system eliminates them.

Inland Drop On Bits

The DropOn™ Bit system makes changing between diamond grinding bit sizes or grits quick and easy and are more economical to own than standard grinding bits.

The DropOn™ adapter is made with a "keyway" on the outer diameter into which the sleeve "keybar" fits. The two parts interlock while the grinder is on and easily separate when the motor is turned off.


The InvisibleSponge™ DropOn™ system combines sponge-less coolant feed with the convenience of DropOn™ bits. You get better coolant dellivery and changing bits or grits takes just seconds, no allen wrenches or tools required! The InvisibleSponge™ system eliminates all the problems associated with sponges: repositioning them, having them jam up the bit, and less than optimum lubrication while grinding.
