Rated 5 out of 5Â by sebt Don't bother with cheap bits!
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.

Rated 5 out of 5Â by Highflier Expensive but good
This drill bit is expensive but solidly built and very sharp. I had 20 holes to cut through 40mm timber and I cut them very quickly. I have no doubt it will last for a long time.

Rated 5 out of 5Â by Asenby Sharp and tough
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.
