Description:
The set contains nine bi-metal hole saws in the most common diameters, including accessories, for mechanics in the construction, container, and pipeline industries. It comes in a well-arranged plastic box which protects against dirt and damage. Operating instructions are included. It is possible to use hole saw EDPs 29113 and 29115 with the adapter and washer, EDP 29070.
 
Advantages:
Cost-effective sawing of round cut-outs.
Alternating tooth pitch prevents chattering during sawing.
High concentricity.
Good chip removal.
The hole saw is conveniently centred and guided via the replaceable bi-metal pilot drill.
Hole saw arbor comes with an ejection spring for improved ejection of the cut material.
 
Recommendations for use:
Observe the recommended rotational speed.
Clamp the pilot drill in the hole saw arbor and make sure that it projects at least 1/8" over the teeth of the hole saw."
When cutting metals, use a high-quality cutting oil, if possible. This facilitates smooth running and extends the hole saw service life. Exception: when working on aluminum, use kerosene instead of cutting oil.
Bi-metal hole saws are suitable for work on stainless steel (INOX). In order to avoid corrosion, remove any particles that develop from the workpiece during work. Clean the workpiece chemically or mechanically (etching/polishing, etc.).
Make sure that all the teeth are applied evenly. To prevent tooth breakage, avoid swinging movements during sawing.
Avoid overheating the saw.
 
Safety notes:
When using shank extensions, the recommended hole saw rotational speed must not be exceeded in order to prevent accidents.
