German Manufactured Heller HSS-Co Cobalt Drill Bits (3.5mm x 70mm)

WIDE APPLICATION M35 Cobalt HSS drill bits are purposely forged to work on hardened materials. Mainly used in cutting through hard metals such as steel, stainless steel, cast iron, high temperature alloy, titanium alloy, hard plastics and woods, and also can be used for softer materials

For drilling particularly tough or hard metal drilling applications such as stainless steel, hardened metal, cast iron, Cr-Ni and special acid resistant steels. Also work very well on standard metals steels, RSG, aluminium, high temperature alloy, titanium alloy, non ferrous metals, plastics and wood.

Worked on Most Material - M35 HSS twist drill bit for the professional machining of metals, stainless steel, cast iron, alloy steel, hard plastics, wood.

As a leading manufacturer for power tools accessories, Bosch offers the ideal accessories for virtually all applications

Professional & Widely Use M35 HSS Cobalt 5% Jobber Drill Bits for Drilling Stainless Steel & Hard Steels. Also can be used for drilling metals and other materials, such as cast iron, copper, high temperature alloy, titanium alloy, aluminum, hard plastics and woods, etc.

High heat and wear resistance

Professional tools Suitable for stainless steel, cast iron, sheet metal, steel, angle iron drilling is widely used in stainless steel, automotive spring steel and die steel drilling has a high finish, high grinding precision, blade sharp and

Package 20Pcs 3.5mm, SALI drill bit set has connectable accessory storage system to optimize storage space

MATERIAL Made of M35 material, includes 5% cobalt, high hardness, stable performance

Notes - Choose the right lubricant can facilitate cutting or cooling, make cutting easier, and improve dimensional accuracy. Please pay attention to the speed adjustment when using the electric drill. The larger the drilling size, the slower the speed requirement.
