Bullard 18961 Turbo Pipeline Grinding Wheel 9 in Zirconia

Product Description

The BULLARD 18961 is a Type 27 depressed-center turbo pipeline wheel engineered for combination cutting and light grinding in a single pass. Built with premium zirconia abrasive, it delivers aggressive stock removal alongside smooth surface control — eliminating the need to swap wheels mid-job. The 9-inch diameter wheel spins at a maximum of 6500 RPM and mounts via a 5/8-11 threaded arbor, making it compatible with standard large-angle grinders. At 1.6 pounds, it is substantial enough for demanding pipeline work without adding fatigue over a full shift. Fabricators, pipefitters, and welding professionals reach for this wheel when a job demands both a clean cut and a finish grind without a tool change.

This wheel is designed for pipeline and heavy fabrication applications where cutting and light grinding occur in the same weld joint or bevel prep sequence. The turbo segment geometry provides smooth tracking along pipe contours and curved surfaces, giving the operator better feedback and reduced chatter compared to a standard flat-face wheel. Typical install scenarios include field pipeline welding, structural steel fabrication, and maintenance grinding on process piping. It is sold individually and is suited for both shop and field use.

Key Features

• Type 27 depressed-center profile allows flush grinding and cutting in tight weld joint access
• Premium zirconia abrasive delivers extended wheel life and aggressive cut rate on steel and stainless
• Turbo segment design reduces chatter and improves control on pipe and curved surfaces
• 5/8-11 threaded arbor fits standard large-angle grinder spindles without an adapter
• 6500 RPM maximum speed rating compatible with common 9-inch grinder drive speeds
• Combination cutting and grinding capability eliminates mid-task wheel changes

Compatibility

Designed as a direct-mount replacement or consumable for standard large-angle grinders accepting a 9-inch, 5/8-11 arbor Type 27 wheel. No input data specified compatible grinder models beyond the arbor and diameter configuration.

Installation Notes

This wheel should be installed and changed only by qualified personnel following ANSI B7.1 and grinder manufacturer guidelines. Inspect the wheel for cracks or chips before mounting — never use a damaged wheel. Power down and disconnect or lock out the grinder before mounting or removing the wheel. Always install the proper guard and wear appropriate PPE, including a face shield rated for grinding operations.
