Pferd Hole saws are made from tough, shatter-proof, sturdy HSS bi-metal. The saw teeth are made from high-quality M42 material. The set contains nine bi-metal hole saws in the most common diameters, including accessories, used in the construction, fabrication and pipeline industries. It is supplied in a clearly structured plastic box which protects against dirt and damage. The operating instructions are included. It is possible to use the 1-3/8” and 1-1/2” diameter hole saws with the supplied adapter and washer.
Cost-effective sawing of round cut-outs.
Chattering during sawing is prevented by the alternating tooth pitch.
Good chip removal.
The hole saw is conveniently centered and guided via the replaceable bi-metal pilot drill.
Hole saw arbor is supplied with an ejection spring for improved ejection of the sawn cut material
Suitable for use with:
Stainless steel (INOX)
Copper, bronze, brass
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 lengthens 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 which develop during work from the workpiece. 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.
