This product is well built

March 06, 2015
This product is well built and simple to use the blades are easy to replace . The only thing that would make it five stars is if the blades could be lowered a bit more because it's difficult to sipn the tire when it still has the stubes on it .
Pros:
  • easy to change blades
  • Simple to use
Cons:
  • blades need to be able to extend more
Yes, I recommend this product.

The gap between blades on each side is about a 1/4" but there is a gap in the center wich means that you have to overlap every other pass .

These blades are .140" apart from each other. You could remove the center blade to make .280" from blade to blade. There is 2 sets of three blades with 5/8" inbetween inside blade on each set

It's used to cut small lines in a tire to help reduce heat build up when racing on dirt tracks .

Sipers quickly and precisely sipe tires for better traction. Units have adjustable sipe depth. Lightweight tool uses standard utility blades and is constructed for heavy duty use. These tools should be handled with care.

This tool doesn't cut groves it just slices the tire, if you want groves you need a tire grover.

Thanks for you question on our Super Siper. This siper makes use of razor blades or like a blade out of a utility knife. The cuts are very hard to even notice in a cold tire. Once the cut heats up it will open a little bit. The siper you are looking at will not cut a 3/16 groove. It is just 6 of those blades that will cut a slit in the thread. If you are wanting to cut 3/16 of an inch grooves I would recommend using Grooving Iron such as our 445-251. It would be make use a #3 blade that can cut 5/32 of an inch or a #4 blade that would cut 7/32 of an inch. It can cut larger grooves as well but that would be the closest to your 3/16 of an inch. The siper you are looking at will not cut a 3/16 groove.
