Pferd 25100116 Bi-Metal Hole Saw LS 16, 16 mm, 1/2-20 UNF Thread, 34 mm Cutting Depth

The Pferd LS bi-metal hole saw is an HSS bimetal hole saw for cutting out holes. This page lists 41 sizes, from LS 16 (16 mm) to LS 152 (152 mm), in two thread versions: 1/2-20 UNF up to LS 30 and 5/8-18 UNF from LS 32.

The catalogue describes these as hole saws made of tough, shatter-proof, sturdy HSS bimetal for cost-effectively cutting out holes, with saw teeth made of M42 (Co8) material (manufacturer-stated).

The alternating tooth pitch gives high concentricity and prevents chatter while sawing, chip removal is good, and the saw is centred and guided by a replaceable HSS pilot drill (manufacturer-stated).

Each item has its own maximum cutting depth and optimum speeds for steel, stainless steel (INOX), non-ferrous metals and plastics, shown in the table below (manufacturer-stated).

Where this product is used

Common specifications

Key specifications

Speeds are the optimum speeds printed in the catalogue. For every size listed, non-ferrous metals and plastics share one figure, shown in each item's specification.

Selecting the right option

Choose the diameter you need, then match the thread. LS 30 and smaller have a 1/2-20 UNF thread and suit hole saw arbors LSS 1 or LSS 4 or the PSL quick-mounting system; LS 32 and larger have a 5/8-18 UNF thread and suit arbor LSS 2 or the PSL system (manufacturer-stated). Fit the saw to its arbor on the Pferd hole saw arbors LSS 1, LSS 2 and LSS 4 page; the pilot drill is on the Pferd pilot drills LSB 6/60 and LSB 6/90 page. In the catalogue the optimum speeds for steel and stainless steel (INOX) fall as the diameter increases, so check the figure for your item and material in the table.
