Serrated Eccentric Drill Bit for Tile, Glass and Hard Materials

Get cleaner holes on tough surfaces without the usual wobble and chipping. This serrated eccentric drill bit brings steady control to tile, glass, marble, wood, plastic, and some concrete jobs.

It keeps your drilling more accurate from the start, so each hole lands where you want it. That means less frustration on delicate materials and a smoother finish on detailed work.

Cleaner drilling on hard surfaces with more control

✅ Cut through brittle materials with less chipping for a neater result

✅ Start holes more precisely on glossy surfaces where bits often wander

✅ Move through demanding jobs faster with more efficient drilling

✅ Work across ceramic, glass, marble, wood, plastic, and some concrete

✅ Use it with hand drills or electric drills for more flexibility on site

✅ Keep drilling stable during longer sessions with better heat dispersal

✅ Choose from multiple diameters for delicate tasks or larger mounting holes

Better control starts with the four-edge serrated structure and carbide alloy core. Together, they keep the cutting path steadier on hard, brittle surfaces where accuracy matters most.

For renovation work, fixture installation, or detailed DIY projects, the dry-drilling capability keeps your workflow simple. You spend less time switching tools and more time getting the job done.

Steady drilling makes each project feel more controlled.

The titanium coating adds wear resistance, which supports repeated use in demanding environments. Available in multiple diameters, it gives you options for both finer work and larger holes.

Fewer tool changes keep your project moving smoothly.

Choose a drill bit that stays steady on tough materials and keeps every hole cleaner.
