The 4.75 mm radius is chosen for narrow grooves on thin profiles and MDF doors. The 6.35 mm radius is the most requested for standard finger pull grooves on kitchen doors. The 9.5 mm radius produces wider grooves on worktops and thick panels, including artificial stone.

R4.75 mm produces a 9.5 mm wide and 6.4 mm deep groove, suitable for thin profiles and MDF doors. R6.35 mm is the standard size for finger pull grooves on kitchen doors, with 12.7 mm width and 9.5 mm depth. R9.5 mm produces the widest groove, 19 mm wide and 12.7 mm deep, for worktops and thick panels.\u003c\/p\u003e\n\u003ch3\u003eIs the M114 compatible with CNC machines as well as handheld routers?\u003c\/h3\u003e\n\u003cp\u003eYes, unlike the M107 series, the M114 is compatible with both handheld routers and CNC machines. The 8 mm shank is standard on both types of machine. The laser marking with maximum RPM on the shank provides the reference for CNC programming.\u003c\/p\u003e\n\u003ch3\u003eHow is it used without a bearing to follow a template?\u003c\/h3\u003e\n\u003cp\u003eWithout an integrated bearing, there are two possible methods: mount an additional bearing on the shank using a stop collar, not included, or use a fixed template guide bushing on the handheld router. The guide bushing is the most common method for template routing with bits without bearings.\u003c\/p\u003e\n\u003ch3\u003eCan the router bit be resharpened?\u003c\/h3\u003e\n\u003cp\u003eYes. The HW cutting edges have a thickness of 2 mm, sufficient for multiple resharpening cycles. For reduced-diameter versions, the minimum thickness is 1 mm. Resharpening is recommended at a specialized center to maintain the U-profile and original balance. The laser-marked parameters on the shank serve as a reference for the sharpening service.\u003c\/p\u003e\n\u003ch3\u003eWhich materials can be machined with the M114?\u003c\/h3\u003e\n\u003cp\u003eThe M114 is compatible with softwood and hardwood, glued wood, plywood, DTD, MDF, laminate, plastic and artificial stone. The PTFE Teflon coating reduces resin build-up when machining synthetic materials and adhesives.\u003c\/p\u003e\n\u003ch3\u003eWhat are the recommended maximum RPM values?\u003c\/h3\u003e\n\u003cp\u003eThe recommended maximum RPM values are specific to each version and are laser-marked on the shank of each individual router bit.
