Drilling Out Cylinder Head Studs - Tooling Question

Joe AutoDrill · 2011-02-14T14:08:15+00:00

If you call me and ask me about drilling some typical manufacturing-related job, I can sell you the equipment, but generally, I don't get into suggesting tooling because there is such a massive number of options available and I figure the tooling manufacturer will be the best one to ask.You don't ask a drill press manufacturer what "bits" to use, right? Same thing here...So, I have a neighbor who runs a large auto repair shop and he was complaining about not being able to find decent tooling at the local supply house. I offered to bring him my McMaster and MSC catalogs tonight as he had never heard of either of them... But now I know what is coming next. "What do you suggest I buy Joe?"So... I know HSS isn't working for him. He breaks the tools all the time, etc. I'm thinking TiN coated will work best for him given the fact that he will never use coolant and will be hand drilling almost all of the time. I'm also thinking left hand spiral so that the occasional stud works itself out easier with the rotational force of the bit... Carbide is presumably out due to the hand drilling and vibration, etc.Any suggestions out there for me to give to him on what to purchase tonight? Limit the suggestions to MSC and McMaster please unless there is a clear cut leader out there I don't know about that these two can't supply.Thanks!Regards,Joe Agro, Jr.(800) 871-502201.908.542.0244Automatic / Pneumatic Drills: Spindle Drills: Tapping: Site:
