Review on Industrial Drill Bits by Drilax174: Diamond Granite Porcelain Bathroom Cutting Tools by Brian Samaiyar
Excellent flotation Hardie Plank (cement board)
This 7/8" diameter Drilax Diamond Coated Hole Saw did a great job with the Hardie Plank (cement board) finish on our patio. Start twisting the bit, hold it at an angle to start, then quickly straighten it once you have the holding groove. Smooth, clean and fast cutting. The comparison price for just a few holes is unbeatable. 7/8" perfect for 1/2" PVC pipe.
Pros
- EASY TO USE Diamond Burs. Start at an angle, go vertical, don't apply too much pressure. Keep the instrument wet to cool.
Cons
- Unbelievable Price
