Description
The DART 25 Piece HSS Cobalt Twist Drill Set is a high-quality set of drill bits designed to handle tough materials with ease. Each bit is made from M35 high-speed steel with 5% cobalt, which makes them highly resistant to heat and wear. This ensures long-lasting sharpness and durability, even when used on hard metals like stainless steel.
Manufactured to DIN338 standards, every drill bit features a 135° split point tip. This design allows for precise drilling without the need for pre-centring, saving time and improving accuracy. The right-hand cutting angle at 30° provides smooth and clean holes while reducing friction and heat build-up.
This set contains 25 drill bits ranging from 1 mm to 13 mm in 0.5 mm increments, making it highly versatile for a variety of projects. It is suitable for drilling sheet metals, non-ferrous metals, steel, stainless steel, brass, and cast iron.

I’ve used MSS Timber Merchants several times now, and I honestly wouldn’t go anywhere else for my timber supplies. The quality of the wood is always excellent, with no warping or defects, and it’s clear they take pride in what they stock. Prices are fair and competitive, and delivery has always been reliable and on time. What impressed me most is the level of customer service — the team are knowledgeable, approachable, and happy to give advice, whether it’s about decking, fencing, or general timber projects. They make the whole process smooth and stress-free. If you’re looking for a trustworthy timber supplier that combines quality products with genuine customer care, MSS Timber is your go to!!!!
