Metal drill bits ground from solid, extremely heat resistant 5% cobalt-alloyed high speed steel produced according to DIN 338.
Suitable for drilling high alloy content steels and metals with tensile strengths over 1000 N/mm² like stainless steel.
QUAD EDGE™ Tip: unique combination of 135° split point and four cutting edges: 135° split point allows for precise & fast drilling start without walking. Four cutting edges create smaller chips to prevent heat build up for longer life.
Variable flute geometry: For faster material ejection. Helps the bit run cooler and prevent it from burning out faster.
Enhanced tapered web: Wider core towards the shank of the drill bit. Strengthens the core to increase overall flute durability.
3-flat shank from 5 mm for better grip and prevents chuck slippage.
Colour: bronze.
Excellent price, easy to order on the website, quick delivery (paid as I needed it quickly but if I hadn’t it was free), well packaged, bought as a gift and recipient very happy
I 'needed' a new phone and A1 Tech offered my choice at a very good price. Buying on-line was straightforward. Communication was excellent and the phone arrived exactly as promised. I also bought a charger which came a couple of days later, but that was fine.
First time heard and ordered from this company and have to say everything went as good as it could
The item was cheaper on here than anywhere else at the time
They kept me informed about the delivery and it arrived when they said
Great service, quick delivery and exactly as described. Not used the phone yet as, being brand new and a gift for my wife, it's not yet been used, but it looks great.
Fantastic company, prices are always great and very competitive. Ordered a few things now and delivery is always really quick. Kept up to date with order tracking and packaged well and safely. Products are exactly what they say they are.
