DIRECT ANSWER
A size-selection guide for M14 electroplated diamond hole saws from 6mm to 100mm, including material, grinder fit, drilling method and chamfering tools.
Choose the diameter from the required finished hole
The SHENGCHI sample series includes 6, 20, 25, 35, 50, 75 and 100mm M14 tools plus a 50mm chamfering tool. The correct size is determined by the required finished hole or edge treatment.
Confirm material and machine
Porcelain, ceramic, granite, marble and quartz can behave differently. Confirm the M14-compatible machine, material thickness and operating method before selecting a tool.
Hole saw versus chamfering tool
A hole saw is selected to create an opening. A chamfering tool is used for edge correction, enlarging or shaping after the opening is made. They should not be treated as the same tool.
