Milwaukee 4932499256 8 Pieces HSS Cobalt Drill Bit Set

Milwaukee 4932499256 HSS Cobalt Drill Bit Set (8 Piece) in PACKOUT Case

Milwaukee 4932499256 is an 8-piece HSS cobalt drill bit set designed for cleaner, more controlled drilling in tough metals, with a heat-resistant cobalt alloy suited to demanding workshop and site tasks. Ideal for engineers, fabricators and tradespeople, this set helps you start holes accurately and keep cutting performance consistent when working on higher-strength materials.

With a QUAD EDGE™ 135° split-point tip and a variable spiral design, the 4932499256 set is built to reduce wandering on start-up and improve swarf removal for smoother drilling. Supplied in a PACKOUT-compatible case for organised storage and quick bit selection.

Key Features

• HSS cobalt construction (5% cobalt): Heat-resistant alloy steel helps maintain performance when drilling demanding metals.
• QUAD EDGE™ 135° split-point tip: Designed for accurate starts and reduced wandering, often removing the need for a pilot hole.
• Four cutting edges: Promotes efficient cutting and helps deliver cleaner results in metal drilling applications.
• DIN 338 ground finish: Precision-ground geometry for consistent drilling and a polished finish.
• Variable spiral design: Helps evacuate chips efficiently and reduce heat build-up during drilling.
• Conical amplifier core: Strengthens toward the shank for improved durability and longer cutting-edge life.
• Three-facet shaft (from 5mm): Helps provide a secure grip in the chuck and reduces slippage under load.
• PACKOUT-compatible case: Robust, organised storage for easy transport and tidy tool control.
