Cratex 1349 C Rubberized Abrasive Taper Point 1in Silicon Carbide

Product Description

The CRATEX 1349 C is a rubberized abrasive point designed for precision deburring, blending, and surface finishing on metal and hard materials. This unmounted taper-shaped point measures 1 inch in maximum diameter and 1-1/4 inches in length, with a 1/4 inch arbor hole for use with a rotary tool, die grinder, or flex shaft machine. The abrasive matrix is silicon carbide in a coarse grade with a 240 grit rating, delivering fast stock removal on ferrous and non-ferrous metals, ceramics, and composites. Machinists, tool-and-die technicians, and metalworking tradespeople use this style of mounted point for controlled hand-finishing in tight or contoured areas.

The taper geometry makes this abrasive point well-suited for reaching into V-grooves, chamfers, port entries, weld seams, and other angular or recessed surfaces where flat or cylindrical media cannot make full contact. It is commonly used in job-shop machining, fabrication shops, and maintenance grinding applications on parts requiring light-to-moderate material removal before final inspection or assembly. The unmounted format means it is used with a separate mandrel or collet chuck matched to the 1/4 inch arbor hole.

Key Features

• Taper shape accesses grooves, chamfers, and angled recesses
• Silicon carbide abrasive for fast cutting on metals, ceramics, and composites
• Coarse grade, 240 grit for efficient stock removal
• Rated to 20,000 RPM for use with standard die grinders and rotary tools
• Unmounted design with 1/4 inch arbor hole - requires separate mandrel
• Rubberized bond cushions vibration and reduces chatter during finishing

Compatibility

Designed for use with any rotary tool, die grinder, or flex shaft machine fitted with a mandrel or collet chuck accepting a 1/4 inch arbor hole. Verify spindle RPM does not exceed 20,000 RPM before mounting.

Installation Notes

Installation and use should be performed by a qualified machinist or tradesperson familiar with rotary abrasive tooling. Power down and de-energize the tool before mounting or removing the point. Secure the point firmly on the mandrel and confirm the assembly is tightened before operating at speed. Always wear appropriate eye protection and follow applicable ANSI B7.1 safety standards for abrasive products.
