Hole saw cutter set promising accurate, clean holes in glass, tile and ceramic. A reassuring choice for DIYers who want neat results without cracking fragile materials. Is flintronic Diamond Drill Bit Set the right addition for occasional projects?
⚡ At a Glance
- • Cutting Quality: Smooth, precise holes thanks to thick diamond coating and chip-clearing design
- • Best for: DIYers, tilers and hobbyists working with glass, ceramic, marble and porcelain
- • Not ideal for: Continuous high-volume industrial production where specialised industrial cutters are required
Diamond-coated cutting edges and nickel-plated carbon-steel construction form a 15-piece set ranging 8mm to 50mm. Large clearance holes help chip removal while water lubrication and cooling are required to avoid overheating.
Clean, precise holes - with thick diamond coating
Diamond grit bonded to the cutting rim concentrates abrasive action at the edge, removing material while reducing stress on surrounding surfaces. The hardened coating resists wear during contact with glass and ceramics.
Neat, low-chipping holes in fragile materials reduce finishing work and lower the risk of cracking during drilling.
Durability and corrosion resistance - with nickel-plated carbon steel
Industrial-grade carbon steel provides structural strength while a nickel-plated finish reduces surface corrosion and wear from coolant exposure. Proper cooling prevents heat-related damage to both bit and workpiece.
A robust build tolerates occasional project use and stays serviceable longer when rinsed and cooled during operation.
Faster drilling and debris clearance - with large clearance holes
Side apertures along each barrel allow water and swarf to exit the cutting area, preventing clogging and maintaining cutting contact. Continuous coolant flow keeps the cutting edge effective.
Quicker drilling sessions with fewer stoppages for cleaning, provided water lubrication is used throughout the job.
