Review: Worked Well for DIY Glass Project - Used one bit from this set to drill holes in 4 glass candle holders for a DIY lamp shade project – it worked really well!

## Features

- 【HIGH QUALITY MATERIAL】Flintronic diamond drill bits are made of industrial-grade high-strength carbon steel, and the surface is nickel-plated, which is effective against corrosion and rust. The diamond surface coating of the drill bit, the coating is thick and uniform, and the wear resistance and life of the hole opener are improved.
- 【PRECISE POSITIONING】Compared with traditional glass hole saws, our hole saws have positioning aids. The pilot bit in the center can help you to position accurately, ensure that the drilling will not slip, won't get stuck, and help to cut precise holes.
- 【CUTTING EFFECT】The diamond surface coating adopts sintering processing method. The cutting edge contains diamond particles from the inside out to ensure that the edge is always sharp. Low cutting resistance and stable drilling create high-precision, smooth cuts with no broken edges for optimal cutting results.
- 【CHIP REMOVAL DESIGN】The cutter head part of our diamond drill adopts a notch design with clearance holes on the side, which facilitates the entry of cooling water, and ensures that chips and other particles escape from the drill hole during operation, so that the hole can be drilled. The process is more convenient and efficient.
- 【WIDE APPLICATION】Flintronic diamond drill bit is suitable for cordless drill, lithium drill, bench drill. Widely used for cutting precise holes in glass, ceramic, porcelain, tile, tile, limestone, slate, marble, pumice and fiberglass.

### ⭐⭐⭐⭐⭐ Good quality item

Good value for money, well made, just done the job

### ⭐⭐⭐⭐ Cheap and does the job
*by J***S on 8 February 2025*

I wasn't expecting much because of the price. I needed a few different sizes and looked on the Screwfix website as that is were I usually buy tools. A 5 piece set from Screwfix was 70 quid so I thought I'd try these first. I don't know how long the diamond edge will last but they cut through ceramic tiles without any problems. I used them in my pillar drill and they cut a clean accurate hole. Definitely worth the money.
