Set of 3 HSS-M35 Steel Cobalt Step Drill Bits with Hex Handle + Case

▶ DESCRIPTION:

The set includes 3 step drills made of high-quality high-speed steel HSS -M35 with the addition of 5% cobalt. The drill bits are designed for precision drilling in metal, plastic, and wood, ensuring durability and reliability in everyday use.

▶ Set contents and dimensions of drill bits:

1 Step drill bit 4 to 32 mm (9 dimensions: 4, 6, 8, 10, 12, 14, 16, 20, 25, 32 mm).

2 Gradual drill bit 4 to 20 mm (9 dimensions: 4, 6, 8, 10, 12, 14, 16, 18, 20 mm)

3 Gradual drill bit 4 to 12 mm (5 dimensions: 4, 6, 8, 10, 12 mm).

▶ Material and durability:

Material – HSS M35 with cobalt:

1 HSS (High-Speed Steel): High-speed steel known for its ability to maintain the sharpness of the cutting edge even at high temperatures.

2 Cobalt additive (5%): Cobalt increases the hardness of the material and its resistance to high temperatures, which is crucial for step drills that are exposed to high thermal and mechanical loads during drilling.

3 Surface: The drill bits have a precision ground surface, which ensures efficient chip evacuation and reduces friction, so that the tool does not overheat as quickly.

▶ Durability of step drills:

✅ High abrasion resistance: HSS M35 steel is much more durable compared to standard HSS steel, which makes these drill bits particularly suitable for drilling into more difficult materials such as stainless steel, carbon steel or colored metals.

✅ Focus retention: Drill blades remain sharp for a long time, even under heavy use, thanks to increased hardness and resistance to deformation.

✅ High temperature resistance: The addition of cobalt allows drill bits to retain their cutting properties when drilling at high speed, which is typical for working with metals.

▶ Application:

✅ Drilling in steel sheets, aluminium, copper, plastics and wood.

✅ Creating holes of different diameters in one working process.

✅ They are suitable for use in table drills, hand drills and cordless drills.

▶ Advantages:

✅ Precision: Accurate and repeatable results when drilling different diameters.

✅ Multifunctionality: One set covers a wide range of hole diameters.

✅ Durability: Longer service life thanks to high quality material.

✅ Easy operation: The gradual design allows you to smoothly increase the diameter of the hole.

The drill bits in this set are equipped with a hexagonal handle, which provides better tool stability in drill and screwdriver holders. Thanks to this design, the tool is more slip-resistant during drilling, especially in materials with high hardness.

The use of HSS M35 steel with cobalt in step drill bits makes them extremely durable and wear-resistant. They are the ideal choice for professional applications where reliability, precision, and long tool life are required, even in harsh environments.
