What customers have to say about our work

“When I first e-mailed you I got a reply the next day advising me with what to purchase. You also went out of your way to get the grinder I required. You also went out of your way to have a normal conversation by e-mail. It looks like to me that you Paul care about small companies like me even though I live in NEW ZEALAND and also larger ones. Paul you are a credit to your company and may you go on to build it larger as you deserve it.”
Denis Roberts (Manager) New Zealand

"I feel I must tell you that I am over the moon with
the TV50 and C-tec cutting cowl. I used it for the first time today, and was amazed how well it
worked. It's worth its weight in gold. Thanks very much."
Regards Phil Hone.

Dust Muzzle Ultra - Heavy Duty

Universal Dust Muzzle Ultra Heavy Duty Grinder Cowl Fits virtually all 100-125mm & 180-230mm electric & pneumatic angle grinders. Both sizes feature "flip-up" sections for grinding close to walls. Manufactured from 6mm thick, flexible thermoplastic the heavy duty cowls install in minutes and are up to 99% efficient. Excellent for wet or dry grinding and polishing,


The Dust Muzzle Ultra - Heavy Duty is available in two sizes: DMHUD5 fits most 100-125mm grinders, the DMUHD8 fits most 180-230mm grinders. The Dust Muzzle Ultra - Heavy Duty is 99% Dust Free when connected to a 1400w Industrial Vacuum such as the TV50 It is the most efficient and durable Dust Muzzle available for angle grinders

How the Heavy Duty Dust Muzzle works
The Dust Muzzle Ultra - Heavy Duty uses a flexible collar, spacer washers and a set of flexible adapter rings to accommodate the entire range of collar diameters and grinding wheel configurations for both the 100-125mm grinders and the 180-230mm grinders.

The main difference between the many brands of grinders is the diameter of the bearing housing. This is where all dust cowls are attached. On 180-230mm grinders, the bearing housings can vary in diameter from 45mm to over 76mm. On the 100-125mm grinders, the bearing housings will vary from 38mm to over 51mm. The Dust Muzzle Ultra - Heavy Duty has solved this problem. The adjustable fingers of the collar compensate for virtually all the differences in these bearing housings.

The Dust Muzzle Ultra Heavy Duty is excellent for grinding fiberglass, concrete, wood, paints and epoxies. It can be used with sandpaper, diamond cup wheels, 200mm soft pads and wet-or-dry polishing pads.

Note: When the Dust Muzzle Ultra Heavy Duty is being used with a 180mm sanding disc, a Zec disc or any other disc that is less than 10mm from top to bottom, it is recommended that the operator purchase an arbor extender so the wheel will position itself correctly in the Dust Muzzle Ultra Heavy Duty.
