PFERD 47927 – Unitized Mounted Point, Cylindrical Shape, W175, 6SF (MH), 1/4″ Shank (10pk)

PFERD 47927 – Unitized Mounted Point, Cylindrical Shape, W175, 6SF (MH), 1/4″ Shank

Multiple heavily compressed, non-woven layers, which are bonded together by a special grain/resin system. The SiC version is ideal for demanding tasks on hard or sensitive materials. The cylindrical shape is ideal for grinding bores, radii and contours.

Applications

Cleaning

Deburring

Step-by-step fine grinding

Roughening

Structuring (matt finishing, brush matting and satin finishing)

Surface work

Features

Cost-effective due to high abrasive performance and durability.

Produces very good surface quality.

Can be profiled as desired, enabling optimal adjustment to the contour.

Materials

Aluminum	Fibre-reinforced thermosetting plastics (GRP, CRP)	Thermoplastics
Brass	Hardened, heat-treated steels over 370 HV (38 HRC)	Titanium
Bronze	Nickel-based alloys (e.g. Inconell and Hastelloy)	Titanium alloys
Cast steel	Stainless steel (INOX)	Zinc
Cobalt-based alloys	Steel materials with a hardness> 54 HRC
Copper	Steels up to 370 HV (< 38 HRC)

Recommendations

For the best performance, use with a recommended peripheral speed of 2,000-4,000 SFPM. This provides an ideal compromise between stock removal rate, surface quality, thermal load on the workpiece and flap wheel/cross buff wear.

Considerably reduce peripheral speed for work on materials with poor heat-conducting properties, e.g. titanium and stainless steel.
