Cuts Fast and Cool
We made our 3M™ Cubitron™ II Depressed Center Grinding Wheel to perform at a level that surpasses competitive wheels in both cut and life to deliver significant gains in productivity. Experience the power of 3M Precision Shaped Grain to provide a cool, extra sharp, quick cut long after other wheels are consumed.

Ideal for Robotic Weld Grinding
In medium and high pressure applications like robotic weld grinding, it's important to choose a high performance abrasive that cuts fast and lasts long. The self fracturing mineral in 3M™ Cubitron™ II Depressed Center Grinding Wheel will keep your robot grinding welds long after other abrasives call it quits, reducing downtime and maximizing efficiency.

Grinding Wheel: Tips for Optimum Use
A grinding wheel is a rigid resin bonded wheel that is approximately 1/4" thick and is useful for removing welds from internal angles. Fiber discs, on the other hand, typically work best for grinding welds on flat surfaces. A grinding wheel must be run on a right angle grinder with a wheel guard that is designed specifically for the size of wheel used. Type 27 wheels have a depressed center to allow grinding at any angle without damaging the surrounding surface with the attachment. The grinding wheel must have a maximum operating speed greater than or equal to the maximum speed of the grinder used.

3M Precision Shaped Grain Maximizes Cutting Potential
3M™ Cubitron™ II products have raised the bar for high performing abrasives. Our team of 3M engineers started with 3M™ ceramic abrasive grain and used proprietary precision shaped grain technology to maximize cutting potential. Precision shaped grain continually fractures into super sharp points and edges that slice cleanly through metal like a knife, rather than plowing as traditional abrasives do, ensuring extended high performance in heavy duty production applications. The grains wear evenly and provide extra long life and consistency with less grinding pressure. We are proud to say that 3M™ Cubitron™ II abrasives outcut and outlast competitive ceramic abrasives, maximizing productivity and minimizing operator fatigue.

Thank you for your feedback. We’re sorry for the frustration this caused. We want to clarify that your order was for one child-size cervical collar, which is what was shipped. The product photo shows both the adult and child models so customers can see the size differences, but each is sold separately.

Our team reached out by phone and email to explain this and offer you the adult size free of charge, but we regret that it left you feeling dissatisfied. If you’d like to discuss further, our management team would be happy to assist. Please contact us at: (800) 637-6606

The website said 1 day when ordering, the reason we purchased from you. It's been 14 days and we still don't have it. The other issue is you were not the lowest priced. I called customer service and they answered my questions but did not seem concerned at all. Actually I remember hearing a snicker or light laugh.

I had a question about the products and was answered quickly and professionally. It was a great experience and look forward to doing more business with you.

Customer care was great. The individual I spoke with regarding a delayed shipment kept me informed over a period of five days. He called me to let me know the reason for the delay, when the item would be shipped and when the item had shipped. The lack of transparency at checkout was a deal breaker. If you charge a customer almost $15 for 2-day shipping then it should not take a week to get the product to the customer. If it takes that long, the company broke the contract.

Easy to find what I needed. I will use enviro safety again.
