Product Description

Milwaukee 4932493868 RED COBALT HSS-Ground Cobalt Metal Drill Bit Set (25 Pieces)

The Milwaukee 4932493868 RED COBALT HSS-Ground Cobalt Metal Drill Bit Set is a 25-piece set, crafted from high-speed steel alloyed with 5% cobalt for extreme heat resistance and durability. Designed according to DIN 338 standards, these bits are ideal for drilling tough metals, including high-alloy steels and stainless steel with tensile strengths over 1000 N/mm². The QUAD EDGE™ Tip combines a 135° split point for precise, fast starts with four cutting edges that reduce heat buildup, extending bit life. The variable flute geometry allows faster material ejection, while an enhanced tapered web strengthens the bit’s core. From 5 mm up, the bits feature a 3-flat shank for added grip and reduced slippage, and they come in a durable bronze color.

4932493868 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 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.
