Started out making a C spanner from 3mm plate, nothing special, just the run of the mill flat plate that bins are made of. Few months back, I bought one of them well packaged hole saw kits from Bunnies, the light bright blue ones, starts with "S". Before using any hole saw, I always drill a pilot hole first, ample supply of cutting fluid to ease the drill bit in. Attached the spankers new hole saw with supplied drill bit, applied more cutting fluid and proceeded to drill through the pilot hole, like I have done countless times before with the Starrit's.
Ping, something flew past my face shield, . Checked the drill bit, chipped on both sides, stuffed, unusable and bin fodder for the bit. Brand new, never been used and it cant drill a hole in soft steel. Found the old Starrit shank and holder, used that instead. My camera does not have a macro function to show the result, tried takeing a close up pic, just comes out blurred.
The other "S" stuff is rubbish in my books.
