2.Craft & Performance
The M14 Four-in-One Chamfer Tool is manufactured through integral one-piece forming and advanced vacuum brazing craft, firmly bonding dense premium emery grit on the layered curved grinding body to avoid sand shedding under continuous heavy load grinding. Built-in cooling wax is pre-set inside the head of the M14 Four-in-One Chamfer Tool, which melts automatically during high-speed rotation to lubricate and cool the contact surface, lowering friction temperature and extending the service life of abrasive grains. The multi-stage curved profile of the M14 Four-in-One Chamfer Tool is precisely shaped with 55mm full effective grinding height, the 38mm wide opening surface supports fast rough grinding, while the 20mm round edge wheel delivers smooth arc finishing. The M14 Four-in-One Chamfer Tool runs steadily without vibration when mounted on M14 angle grinders, evenly polishing stone surfaces without chipping or cracking slabs, and the compact 8mm small top opening is designed for fine trimming of tiny hole edges. Uniform brazing coating guarantees consistent grinding efficiency from top to bottom of the M14 Four-in-One Chamfer Tool, eliminating uneven wear and frequent tool replacement.
Application
The versatile M14 Four-in-One Chamfer Tool is widely used in stone factory processing, home tile renovation and custom countertop production, specially designed for hard stone and ceramic materials. It works perfectly on quartz stone, granite, natural marble, polished vitrified tile, common ceramic tile and artificial stone. The M14 Four-in-One Chamfer Tool handles full-process stone hole machining: drill initial holes with the tiny top tip, expand apertures via the main conical surface, smooth sharp edges with the round wheel and finish uniform chamfers for beautiful round corners. For tilers, stone fabricators and DIY stone workers, the M14 Four-in-One Chamfer Tool replaces four separate single-function tools, saving storage space and improving construction efficiency for countertop sink holes, wall tile mounting holes and stone craft trimming.
