HSS-Co. Bi-metal holesaws set in case type 3

Contents of the case:

HSS-Co. 8% Bi-Metal hole saws: 19 + 22 + 29 + 38 + 44 + 57 mm

Hole saw drive adapter: 14 - 30 mm

Hole saw drive adapter: 32 - 200 mm

Bimetall hole saws Co 8% are drilling tools with an extremely wide range of use.

• Unlike HSS bimetall hole saws, cobalt bimetal hole saws can also be used in metals with strengths higher than 700N / m2, stainless steel and Hardox steel (up to 1000N / mm2). However, they are less suitable for other materials (plasterboard, wood, etc.).
• Thanks to a number of different adapters, it is possible to use cordless screwdrivers, hand and stand drills as well as small electropneumatic hammers.

Design:

• material: HSS Co. 8%
• cutting depth 40-45 mm
• variable teeth distribution
• hole saws up to 30 mm diameter are with a 1/2 "- 20 UNF thread
• hole saws from a diameter of 32 mm are with a thread size 5/8 "- 18 UNF

Notice:

• before drilling, check the recommended speed (see speed table) and when drilling into metal, use a cooling medium (cutting oil or emulsion)

Used in: Alloyed and non-alloyed steels (up to 1.000 N/mm strength), Hardox steel, high chromium alloyed steels such as stainless steel, steels resistant to rusts and acids, non-ferrous and light metals.

Used in: alloyed and non-alloyed steels with strength up to 700N / m2, stainless steels A2, iron, non-ferrous metals, plastics, wood, wood with nails, coated chipboard, plasterboard
