Dependable, well-balanced, long-wearing wheels for general shop use. Carefully selected, high grade cotton sheeting assembled to give maximum cutting action. Continuous spiral sewing with 1/4" spacing.
BP-36 is a softer wheel for fine buffing and thicker material.
BP-40 is a harder wheel for edges and removing surface scratches.
Larger wheels have a higher surface speed and cut faster.
Cushion sewn buffs have two or more circles of sewing between the arbor hole and the face, giving them a medium density. For light cutting and general finishing applications.
The 4" wheel is to be used on a hand drill, do not use a cordless drill! The 6" is to be use on a bench grinder. An arbor is available for the 4" wheel to your drill.
