Please add water for coolant and drill slowly 2. Start drill at 45 Degree to surface and align to 90 Degree as hole forms 3. Never use drills while machine is in hammer action. 4. Holes Require No Futher Work As Cutting Is Clean Please add the water to cool the drill bit while drilling hole process The Diamond Hole Saw Does NOT Have Center Pilot Drill There is no need for a Pilot Drill Bit, because pilots are not safe for glass/stone. How to use a hand drill to drill holes in the glass/tile/stone? Step 1. The bit on the glass/tile/stone 45 degree, open a half-moon notch on it Step 2. Slowly up the bit to 60 degrees, and then gently drill Step 3. Reached 90 degrees, continue to drill Step 4. Drill through the glass/tile/stone finally, the technique requires a β€œwobble” of the drill rather that steady pressure straight on We Can List Any Size and Amount Of This Product: Hole diameter from 0.4mm to 230mm Review: Helped remove a stuck bolt quicker than expected - The tip of my bolt extractor snapped off when using it on one of the bolts on the underside of my lawn mower deck (the bolt head broke off), the bolt was old and rusted. Two days of penetration oil didn't do enough. So, the bolt extractor was used to get the bolt out...that was a no-go when the tip snapped off and was fully stuck in the pilot hole. These bits were purchased to see if they'd help in wearing down enough material to get the bolt extractor tip out before I drilled through the bolt and re-tapped it. The extractor being a far harder steel made using my usual drill bits a no-go in attempting without something like diamond coated hole saw bits. So, with as many as come in this pack, I figured why not? It's cheap and a useful test. I went through about 4 of these, ensuring I kept the bits cooled with a container of water (dipping the bit in ever ~5 seconds of drilling), over the course of about an hour. Gotta go slow, don't apply more than a very light pressure if any, let the hole saw do its thing by abrasing the metal slowly. Worked great, the extractor tip fell right out eventually, and I've got a bunch more of these for the next time! Review: Great bit - Five star! I've only used one drill bit but so far this FAR outperforms the dremel glass drill bit. I have so far drilled more than 15 holes with the first drill bit of the package. 15 holes and it still has some life! I have drilled through rock, glass, and shell. In comparison the dremel glass drill bit was only used on glass and I maybe drilled 12 holes before it was useless. The size of the hole this bit makes is a little larger than I expected but I take it into consideration for what I'm drilling. The one complaint I read about and is a bit of a problem is the length of the hollow core of the bit. After each use I have to use a metal pick to punch out the stone or glass piece that is in the bit by sticking a metal pick through the small side hole. And if whatever you're drilling through is thicker than the hollow core of the bit you have to stop short and break off the nub inside the hole before proceeding. This bit is so much better and cheaper than the dremel bit that I will happily adjust for the two issues I mentioned above. ## Features - Hole Diameter: 2.5mm (close to 3/32"); Total length: 42mm (1-21/32"); Drill depth: 3mm(1/8") - The diamond coated hole saw suitable for use in drill hole on glass, marble, tile or granite - Use with water as a lubricant, holes require No futher work as cutting is clean - NOT have center pilot drill;Start drill at 45 degree to surface and align to 90 degree as hole forms - Product Name: diamond hole saw, diamond drill bit for tile, hole saw ceramic tile ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B075J9MB8J | | Best Sellers Rank | #85,338 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #196 in Hole Saws | | Brand | JINGLING | | Brand Name | JINGLING | | Customer Reviews | 4.3 out of 5 stars 717 Reviews | | Cutting Angle String | 60 degrees | | Cutting Diameter | 2.5 millimeters | | Finish Type | Diamond | | Finish Types | Diamond | | Manufacturer | JINGLING | | Material | Carbon Steel , Diamond | | Material Type | Carbon Steel, Diamond | | Minimum Bore Diameter | 2.5 millimeters | | Model | 708747505412 | | Number of Pieces | 20 | | Part Number | 708747505412 | | Set Name | 20-Piece Set | | Shank Type | Straight | | Surface Recommendation | Glass,Stone | | Tool Flute Type | Straight | | UPC | 708747505412 | | Unit Count | 20 Count | ## Product Details - **Cutting Angle String:** 60 Degrees - **Cutting Diameter:** 2.5 Millimeters - **Finish Type:** Diamond - **Material:** Carbon Steel, Diamond - **Shank Type:** Straight ## Images ![JINGLING 2.5mm Diamond Drill Bits for Glass, 3/32" Diamond Drill Bit, Hole Saw Drilling Tools for Stone Tile Pack of 20Pcs - Image 1](https://m.media-amazon.com/images/I/61swJslMwsL.jpg) ![JINGLING 2.5mm Diamond Drill Bits for Glass, 3/32" Diamond Drill Bit, Hole Saw Drilling Tools for Stone Tile Pack of 20Pcs - Image 2](https://m.media-amazon.com/images/I/71uySYcTbHL.jpg) ![JINGLING 2.5mm Diamond Drill Bits for Glass, 3/32" Diamond Drill Bit, Hole Saw Drilling Tools for Stone Tile Pack of 20Pcs - Image 3](https://m.media-amazon.com/images/I/71vbMHdrZ8L.jpg) ![JINGLING 2.5mm Diamond Drill Bits for Glass, 3/32" Diamond Drill Bit, Hole Saw Drilling Tools for Stone Tile Pack of 20Pcs - Image 4](https://m.media-amazon.com/images/I/61Tgeu9iv0L.jpg) ![JINGLING 2.5mm Diamond Drill Bits for Glass, 3/32" Diamond Drill Bit, Hole Saw Drilling Tools for Stone Tile Pack of 20Pcs - Image 5](https://m.media-amazon.com/images/I/61whqHby+NL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Helped remove a stuck bolt quicker than expected *by S***X on July 15, 2024* The tip of my bolt extractor snapped off when using it on one of the bolts on the underside of my lawn mower deck (the bolt head broke off), the bolt was old and rusted.
