Bi-metal hole saw 14 pcs set KAMtools

Application:

Bi-metal hole saw are used for drilling wood, polymeric materials, plasterboard, non-ferrous metals, steel
and stainless steel.
The teeth of the hole saw are made of high quality HSS steel on a spring steel backing. The use of TWO
types of steel defines these items as BIMETAL. Bi-metal hole saws achieve good results when cutting
steel (up to 1000 N/mm2) up to a maximum of 5.0 mm and with stainless steel up to a maximum of 1.5
mm. With softer materials, a cutting depth of up to 38.0 mm can be achieved. A groove cut into the
cylindrical surface serves to facilitate the removal of material remaining in the tool.
Make sure the centering adapter is the correct size for the hole saw being used. Always make sure that
the drilling bit shows 5 to 25mm in front of the teeth of the hole saw, depending on the size of the saw.
Follow the tool RPM recommendations on the package, for the materials being cut, for the appropriate
diameter of the bit being used. Use the hole saw to drill only the materials specified on the product label.
Inspect the hole saw before use in the power tool - if there is excessive wear, the tool is bent, the teeth
are broken or damaged, replace the hole saw before use. Use a driller that is equipped with a support
handle and start drilling with light pressure. Important instructions and warnings are contained in the
power tool's "Instructions for Use" - please refer to the power tool's "Instructions for Use" before using it
with the hole saw set. Failure to follow all safety instructions, warnings and recommendations during use
by the power tool manufacturer may result in serious personal injury. To minimize the risk of serious
injury, always use eye/respiratory protection and other PPE.
Hole saws MUST NOT BE USED IN HAMMER OR IMPACT MODE - only drill in standard rotary drilling
mode or the tool may be damaged/broken and may increase the likelihood of injury to the user.
