High Speed Steel Step drills Hole Cutter Carpentry Equipment Repair Accessories
Details:
*100% brand new and high quality
*Made of high speed steel,with molybdenum and cobalt added to creates a hardened alloy, measures hardness up to 67, for much faster cutting and extra longer service life, with up to twelve times compared to an average HSS drill.
*No center punch required - the 135 °Quick-Cut points are self-centering and penetrate quickly with less pressure. Will not "walk" or "wander"
*Extremely heat resistant; Straight shaft ensures firm holding and accurate centering, fit for standard drill chucks and regular round collet chucks.
*Particularly successful in cutting through hard metals such as stainless steel and cast iron, although they can be used for softer materials, too.
*Different types of drills are used holes in different types of materials.
*This set of M35 cobalt steel drills are particularly successful in cutting through hard metals such as stainless steel and cast iron, although they can be used for softer materials, too.
*Cobalt drills are not made from pure cobalt, but rather a steel alloy with a certain percentage of cobalt. The 5 percent alloy is known as M35 grade.
*The cobalt increases the strength of the steel and makes it more heat resistant; This is an important factor in drilling hard materials because the friction of metals against metal can cause high temperatures that damage the material or the drill.
*Cobalt drills are more expensive than other drills, but if you regularly drill through metal, they are a good investment because they tend to last longer.
*Color: Copper (As Pictures Show)
*Material: HSS
*Size:
4-12mm: 5 steps (4mm, 6mm, 8mm, 10mm, 12mm)
4-20mm: 9 steps (4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 14mm, 16mm, 18mm, 20mm)
4-32mm: 15 steps (4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 24mm, 26mm, 28mm, 30mm, 32mm)
Note:
1.When drilling holes in stainless steel, you can use hand drills and bench drills, hand drills can open boards within 1mm, and bench drills can open 2-3mm boards.
2.When the hole is opened to stainless steel, the speed cannot be fast, it can be a few hundred revolutions.
3.It is best to cool with water or cutting fluid during processing, which can effectively extend the life of the drill.
