Titan HSS Jobber Drill Bits 10mm Pack of 5
Get what you pay for...
On checkout someone said 'those should be called one-jobbers cos that's all they're good for' but my experience, drilling through the 8mm thick flange of a steel beam, is that they'll get there in the end... made 3 holes before I'd blunted the bit and had to move on to the next... so I bought a Dewalt 10mm Extreme 2 HSS bit and it drilled through like butter at 4 times the speed with no sign of blunting yet.
Conclusion: probably great for light duty, not so good for heavy duty/ntensive steel drilling

10MM metal drill bits
Had to drill 8 holes through an I beam.
Bought a pack of 5 of these drill bits to do the task with the intention of burning them all out.
Used wd40 as a spay lube when drilling on a slow speed so i wouldn't burn them out too quickly as i had 8 holes and 5 bits.
Very surprised to find one drill bit cut 8 holes and would have done more if needed as the drill bit was as sharp as what it was at the start.
Defo use again, decent quality for not much money.
