The KDM110 Keep-Nut Drilling Machine from Chemical Concepts is a lightweight precision tool for drilling panels and countertops. This machine will enable any operator to repeatedly and efficiently drill holes with the correct dimensions for use with the Keep-Nut anchoring system. Using an array of compatible bits, the machine can prepare holes in a variety of hard surfaces, including granite, marble, engineered stone, UHPC, porcelain, Dekton, glass and composites. The vacuum-foot allows secure attachment to rough surfaces, including unpolished granite and textured ceramics. This water-cooled pneumatic machine requires only a single airline and a water feed to operate. Use with thin-wall core bits to drill faucet holes in record time without a CNC.
- Fast efficient drilling on hard surfaces
- Lightweight and easy to operate
- Vacuum-foot for secure attachment to rough or even vertical surfaces
- Water cooled and air-operated
- Built in depth stop for precise repeatable results
- Drill holes in granite for sink install
Keep-Nut is a press-in threaded insert that mechanically anchors to provide permanent threads in panels or countertops made of marble, granite, composites, carbon, Corian, HPL, glass and others solid surface materials.
The Keep-Nut insert is specifically developed to fasten ventilated facades, wall-coverings, décor, furniture, under-mount sinks, as well as a variety of other applications.
The Keep-Nut is manufactured in stainless steel and consists of a threaded bush, a set of toothed spring washers (crowns) and a plastic ring holding the parts together. Available in different lengths to fit several different panel thicknesses, Keep-Nut can be installed quickly by drilling the material to the correct hole diameter and pressing in the insert.
Keep-Nut inserts have several advantages. The preparation needed is just a cylindrical hole drilled by CNC or a grinder/polisher. In addition, assembly by pressure is quick and easy and does not require use of any adhesives.
