Premium 8 Piece HSS-Cobalt Metal Drill Bit Set with Case

Product Description

When you need to drill through hard metals that produce significant amounts of heat at high speeds, nothing will do a more efficient job than a Premium High Speed Steel-Cobalt Metal Drill Bit. Made from a 5% cobalt alloy, these high-performance bits are extremely heat resistant and durable, with quad edge tips that allow for much more precise centering and a 135° split point to reduce "walking".

Extremely versatile, these bits are capable of drilling through high-alloy-content steels and metals with tensile strengths exceeding 1000 N/mm² smoothly and efficiently, including mild steel, aluminum, brass, copper, and even stainless steel. This drill bit set is popular in workshops, on construction sites, and for home projects because it maintains its sharp cutting edge at high speeds and is less prone to breakage than other drill bit types. Use this 8-piece metal drill bit set to create holes of a range of different diameters in a range of materials!

Features

• 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 exceeding 1000 N/mm², such as stainless steel.
• QUAD EDGE™ Tip: A unique combination of a 135° split point and four cutting edges. The 135° split point allows for a precise & fast drilling start without walking. Four cutting edges create smaller chips, preventing heat buildup and extending the tool's life.
• Variable flute geometry for faster material ejection. Helps the bit run cooler and prevents 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.
