3M 7010492380 | 1.250" Center Hole Diameter x 4.000" Overall Diameter x 0.063" Thickness x 664BL Wheel Type 3A1 Resin Bond Diamond Wheel

3M cut-off wheel 664BL is used to trim carbide cutting tool blanks to length for the cutting tool manufacturing industry.

• The 3M cut-off wheel 664BL is designed for trimming carbide tool blanks to length. This wheel offers a balance between cut rate, form retention and wheel life and is available in a 120 grit diamond. Water based coolant is required. The use of coolant is critical for it removes heat away from the workpiece and wheel, adds lubricity reducing grinding friction and helps to clear away swarf.

• The abrasive surface of the 3M cut-off wheel 664BL is the periphery, where it is coated with diamond to a depth of .25". This wheel generally cuts radially through the workpiece.

• The 3M cut-off wheel 664BL is part of the broad portfolio of superabrasive wheels, including general-purpose and standard CNC grinding wheels, backed by technical support, available in stock, ready for shipment.
• 3M technical support will always work closely with you to find the right configuration of features to meet your target parameters consistently and efficiently or engineer a product that will.
• Diamond and CBN superabrasive wheels are designed for today's most challenging applications, from grinding hardened steels and superalloys to finishing materials like glass, ceramics and tough composites in automotive, aerospace, oil and gas, primary metal, medical and other areas where machining with conventional cutting materials is not cost-effective because of the materials which need to be machined (glass, ceramics, carbides, etc).
• 3M has the tools you need to achieve stringent geometry tolerances and finish specs, part after part.

Features:

• Resin bond diamond abrasive construction
• Designed to provide a balance of good cut and form retention
• Used for trimming off carbide blanks to length
• Designed for use with water based coolants
• In stock and available for fast two-day shipping from within the US
