Sintered
Reference drilling holes quantity:3000-5000 holes. Suit For:
Flat glass, safety glass, tempered glass, architectural glass, frosted glass, patterned glass, Insulated glass, laminated glass, glass brick, optical glass, Auto Glass, solar glass, grnite, marble etc stone.
Usage:
glass drilling, tile drilling, marble/granite drilling
Machine:
Benching drilling&professional drilling machine, such as Bavelloni, Bottero, Glassline, Schiatti, etc machine
Feature:
extremely high speed, No chipping& maximum working life, save cost, and stable & reliable working.
In order to get maximum output and to reduce breakage / damage during drilling.
