Diamond Glass Drill Bit for Clean Hole Drilling

Quick answer: ZHUIFENG diamond glass drill bits are made with diamond and copper powder formed into a ring-shaped cutting head and bonded to the body through a high-temperature sintering process. Available diameters cover approximately 5–70 mm; confirm hole diameter, glass thickness, machine alignment, connection and cooling before quotation.

What this product is used for

Glass hole drilling for glass processors using diamond core drill bits. Confirm machine alignment, G1/2 connection, hole diameter, glass thickness and internal water cooling before quotation.

Drilling edge-chipping troubleshooting

Customers often see glass chipping as soon as the drill bit enters the glass, then spend hours adjusting the machine, changing parameters and checking material without finding the source. During on-site troubleshooting, we found the drill body was not perpendicular during rotation and the machine itself was tilted. This directly affects dynamic balance, so uneven force at high speed shifts the bit on contact and produces rough, chipped holes.

After replacing the tool with a ZHUIFENG integral diamond glass drill bit, the test run showed smooth holes without edge chipping and stable machine operation. When drilling problems recur, confirm drill-body alignment, machine level, cooling, connection and drill quality before changing more process parameters.

Buyer questions

Frequently Asked Questions

How to drill holes in glass without cracking it?

Secure the glass firmly on a soft support. Use low drill speed and constant water cooling. Start at a tilted angle to make a pilot indent, then straighten the bit. Apply light, steady pressure and stop drilling before breaking through the back side.

What tool can I use to drill holes in glass?

A standard electric drill or cordless drill works. Diamond core drills are preferred for larger holes.

What type of drill bit is best for drilling holes in glass?

Diamond-tipped core bits and spear-point tungsten carbide glass drill bits are the best choices.

Do I need a special drill bit for glass?

Yes. Regular metal or wood drill bits will chip and crack glass. You must use dedicated glass drill bits.
