This product has been used over the past few months for a variety of cutting jobs including York Stone which can be more difficult yo core through than steel reinforced concrete and this product coped remarkable well compared to another brand and type I have been using over the last 6 years costing over twice the price.
PUNK HSS-G Drill Bits are fully ground hardened with a split point tip, which reduces the need for pilot holes up to 10mm diameter. HSS-G treatment strengthens the bit to deliver up to 40% faster drilling than standard rolled drill bits
