M14 Diamond Beveling Cone
M14 Diamond Beveling Cone — Clean, Smooth Hole Edges
Fix Rough Holes in Seconds
Vacuum-brazed diamond cone designed to chamfer, enlarge and deburr existing holes on tile, porcelain, marble, granite and ceramics. Enjoy a crisp, high-end finish with fewer chips and less waste.
Two Sizes for More Control
Choose between 35mm (1.38") and 50mm (1.97") base diameter to match your task—from faucet cutouts to larger pipe openings.
Built to Last
High diamond concentration and vacuum-brazed bond deliver fast cutting and long life. Works dry or wet—water further reduces dust and heat on hard porcelain.
Simple to Use
Thread onto your M14 angle grinder, touch the edge with a soft, steady motion, and let the diamond do the work. Optional adapter lets you fit 5/8"-11 grinders (bundle option).

FAQ
Q1: Can this cone drill new holes?
A: No. It is for beveling, enlarging and smoothing existing holes.
Q2: Will it fit my grinder?
A: It fits M14 spindles directly. If your grinder is 5/8"-11, choose the bundle with the adapter.
Q3: Which size should I choose?
A: 35mm for smaller openings and fine edge work; 50mm for faster stock removal and larger cutouts.
Q4: Dry or wet?
A: Both. Wet cutting is recommended for hard porcelain to reduce dust and heat and get the smoothest edge.
Q5: Any operating tips?
A: Use medium speed and light, even pressure. Keep the cone moving to avoid flat spots and let the diamond cut naturally.
