"Drilling a 100mm deep hole through end grain of hardwood. The other bit I was using cost GBP3.00. It was so bad I only got 8mm in before giving up: the bit was overheating and moving about dangerously. The difference using this bit is unbelievable. Finished in 5 mins, including pauses to clear waste. For a heavy job, pay more to buy this bit and do it properly, quickly and safely."
"Needed a bit to cut a hole through fibre glass and wood composite (boat hull). This was an excellent choice - very sturdy so no risk of the cutters folding over, razor sharp giving a clean cut right through the material and provided a clean finish on the "out" edge with no splitting.
Not cheap but as ever you get what you pay for and this will prove a sound investment."
"Good Product,but it was expensive for a basic one off use,I would have bought a cheaper one but not available in this size.Would recommend that Screwfix try to find a cheaper version for people like me."
