Bi-metal hole saw OREN HSS-Co. 8% 28 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

What to combine with:

• Depending on the diameter of the hole saw and the tools you work with, the hole saw must be combined with the appropriate type of adapter (ordering No. 5102)
• All adapters we offer are supplied with a pilot bit. However, you can also buy the pilot bit separately if  necessary (ordering No. 5103)
• For better removal of the drilled material from the hole saw,  we recommend attaching a compression spring to the pilot bit (ordering No. 5105-2)
• If the drilled material is less accessible, it is possible to use an extension for Bi-Metal hole saws  (ordering No. 5104)

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.

Supplied with plastic hangers.
