US PRO Industrial 7088 13 Piece M35 Cobalt Metric Drill Bits Set

The US PRO Industrial 7088 13 Piece M35 Cobalt Metric Drill Bits Set is an engineering quality drill bit set developed for demanding drilling applications. Manufactured from M35 high speed steel with 5 percent cobalt content, these drill bits are designed to deliver extended tool life and superior cutting performance, especially when working with tough materials.

Cobalt alloy drill bits are well known for their ability to withstand higher temperatures without losing hardness. This makes them particularly effective for drilling stainless steel, high tensile steel, hardened steel, and high alloy metals. The fully ground construction ensures consistent diameter accuracy and smooth cutting action across all sizes in the set.

Each drill bit features a 135 degree split point tip, which allows fast and accurate centring without the need for excessive pressure or pilot drilling. This design reduces walking on the material surface and improves drilling efficiency, particularly when working with harder metals. The DIN 338 standard ensures reliable length and performance consistency.

Finished with an amber surface treatment and hardened to HRC 65 to 67, these drill bits are built for durability and precision. The set covers a useful range of metric sizes, making it suitable for engineering work, automotive repairs, fabrication, and general workshop use where high performance drilling is required.
