Full details
The JCB DiamondTech Hole Saw 25mm is a professional-grade drilling solution designed for tradespeople and DIY enthusiasts who need to bore precise holes into exceptionally hard materials like porcelain, granite, and glass. Its core strength lies in its high-grade diamond-tipped teeth which provide rapid, splinter-free cuts, though users should note that consistent water cooling is required to maintain the integrity of the diamond bonding during heavy-duty use.

FAQs
Can I use this on wood or metal?
This tool is specifically engineered for masonry, tile, and stone. While it may cut wood, it is not optimized for it and the diamond tips will perform best on mineral-based surfaces.
Do I need a pilot drill bit?
No, this hole saw design is intended for use by carefully starting at an angle to create a pilot groove in the material.
Is this compatible with my cordless drill?
Yes, it is compatible with most standard cordless and corded drills as long as the drill has a standard chuck.
Why did my diamond tips wear down quickly?
Premature wear is almost always caused by operating without water cooling or using the hammer action on your drill.
Is this safe for tempered glass?
No, you should never attempt to cut tempered glass as it will shatter instantly upon contact.
Troubleshooting
The hole saw is not biting into the material surface
Ensure you are not using hammer mode; diamond hole saws require rotation only. Start the cut at a slight angle to create a groove before straightening the drill.
Excessive smoke or overheating during cutting
The drill speed is likely too high or there is insufficient cooling. Apply water to the cut zone and reduce the RPM of the drill.
Pros and Cons
Pros
- Capable of cutting through extremely hard materials like granite and marble
- Significantly longer service life compared to standard alternatives
- Provides clean, chip-free hole edges
- Compatible with common power drill setups
Cons
- Requires active cooling for optimal longevity
- Not intended for use with standard impact drivers
- May require slower RPMs to prevent overheating
Setup, Compatibility & Care
To ensure peak performance, secure the hole saw into your drill's chuck, ensuring the shank is centered and tightened firmly. Use a standard drill in rotation-only mode; do not use the hammer or impact setting, as the percussive force can shatter the diamond segments. After use, inspect the tool for debris, clean with a soft brush, and store in a dry place to prevent corrosion on the alloy body. Avoid excessive heat buildup by periodically lifting the hole saw from the cut to allow for debris clearance and cooling.
