When do I drill? Which bur should I use? Are carbide burs really better than diamond burs? While the answer may not make a difference in whether you land a customer or not, the questions are worthy of consideration. By the end of this article, I hope to have cleared up any confusion in regard to bur selection.
“When do I need to drill a break?”
We at Delta Kits recommend drilling during the windshield repair process in three situations: (1) those where you are unable to get the resin to flow into the break, (2) to anchor a crack longer than a couple of inches in length, and (3) when a pit must be capped for the injector to seal properly.
In most cases, repair resin will be able to fill the break if you are properly using Delta Kits equipment, even when there is very little glass missing from the impact point. Many technicians drill the break to create a large channel so the resin will flow more easily. This does speed up the repair, but it also affects the repair cosmetically. Each time you drill a break there will be a visible drill hole. It is up to you to decide if the cosmetic difference is worth the extra couple of minutes. To me, it is definitely worth the wait if the result is a better cosmetic appearance.
Every once in a while you come across a chip that doesn’t have enough glass missing from the impact point to inject the resin. In those instances, just drill through the center of the impact point or into an existing air pocket.
You may also want to drill the end of long cracks to help stop them from running as they are being filled with resin and add additional strength to the completed repair. After drilling the end of the crack (actually about 1/32″ past the end of the crack), follow your slide hammer or spring hammer instructions to create a mini bull’s-eye and fill it with resin. Do not drill past the first layer of glass. The spring hammer includes a handy depth gauge that helps you drill to the perfect depth for making a mini bull’s-eye.
Finally, if you have encountered an impact pit…. Continue Reading
