FSPIN300 Flaring Tool Drill Bit Set With 1/4ββ 3/8ββ 1/2ββ 5/8ββ 3/4" Bits. 5 Pieces Set with the most common HVAC tubing diameters. Revolutionizing system for molding tubes using heat by friction Way more surface of contact between the flare and the valve. Right flaring size, every single time Up to 10x faster than the conventional tools: flares in 5 seconds!. Preserves copper/aluminum malleability while doing the flaring, avoiding cracks and leakages.
Big fire. You just need to make sure the drill bit is perfectly straight with the copper and that you are flaring high quality copper (made in the USA) and not cheap thin wall copper (made in China). Also, use gloves as the copper gets very hot about 3 feet from the torch.
Bought for a mini split thinking it would be quick and easy. level and straight These 2 elements need to be done to get a proper flare, not to mention the copper pipe gets very hot in use. If you're not careful you'll end up with a bad bell and burn. It's not worth it. Sent it back, but hey, if you think there are 2 things you can do to get Flash without getting burned and can afford it, knocking yourself out might work for you
This flaring tool is perfect, no fiddling with screw handles. What I also like is that you don't have to deburr it, it's just one and done. The bell to bell fit is always perfect (or at least the limited number of times I've used it). Works with my Makita cordless drill at high speeds, around 2200 rpm. The manufacturer requires a drilling speed of at least 1800 rpm in order to obtain the necessary frictional heat. I only make my own hands so it should last forever, can't tell how long it willβ¦
