Overview
Cut-off wheels for metallographic sample preparation designed to provide reliable, clean cuts across a wide range of materials. Available in premium grades with different abrasive materials and bond types to optimise cutting performance, lifetime and quality of the cut surface.

QPREP Premium Aluminium oxide cut-off wheels

• Bond: resin / rubber
• Coverage: suitable for a wide range of materials from 30 HV to >650 HV
• Long wheel lifetime and low wear
• Premium abrasive particles deliver very fine cutting surfaces, reducing subsequent grinding effort
• The synthetic resin bond allows dull abrasive particles to break out evenly during cutting

Recommended applications

• Cutting of most materials (broad material range including harder ferrous materials)

QPREP Premium Silicon carbide cut-off wheel

• Bond: resin
• Silicon carbide particles (lower hardness than aluminium oxide) optimised for soft and non-ferrous materials
• Optimised cutting performance for non-ferrous and ductile metals
• Long lifetime and low wear

Recommended applications

• QPREP Premium silicon carbide cutting disc NF-A: soft (e.g., copper, aluminium, brass) and medium-hard non-ferrous metals and alloys and hard non-metallic materials (e.g., glass, stone)
• QPREP Premium silicon carbide cutting disc Ti-A: non-ferrous metals, titanium alloys (e.g., Ti6Al4V, Ti5Al2.5Sn) and refractory metals (e.g., molybdenum, tantalum, niobium)

Product advantages (general)

• Wide application range thanks to different abrasive types and bonds
• Long life and low wear reduce running costs
• High-quality abrasive grains produce fine cutting surfaces and shorten subsequent preparation steps
• Bond technologies designed for even break-out of spent grains improving cutting consistency
