  • General | Guhring and Guehring? - Practical Machinist
    I recently purchased a small lot of 10 Guhring drill bits, all new (Ebay) On closer inspection, I noticed that 3 of the drill bits had the name Guehring instead of Guhring Some bits came with the plastic tubes and all said Guhring on them They all look legit, drill point geometry, numbers, design of shanks etc
  • Guhring drill quality problems - Practical Machinist
    Listen, I am the first one to say that Guhring makes a top notch drill, but I think I may try something else in the near future We mostly use Guhring for HSS powdered metal drills and use GARR for carbide drills Anyway, we keep having problems with the recently purchased Guhring drills They keep cutting oversize I am not sure why
  • CNC Machining | Guhring Drills - Practical Machinist
    2 Guhring stated that they can meet these requirements with item 205 with fire coating 3 GSC used Guhring item 205 from late in 2009 until middle 2010 and had no problem GSC was happy with the cost per hole drilled 4 Middle 2010, Guhring changed the point grind of the Guhring item 205 and it stopped working in our application
  • Opinions on Guhring cutters please - Practical Machinist
    I'm a big Guhring fan, good gear never had anything that didn't do what it said it would on the tin However for good value performance and service Cutwell takes a lot of beating, their YG1 and Korloy ranges have kept me fed
  • Small Drill Speeds Feeds-Guhring drills - Practical Machinist
    Speeds and feeds sound fine Good luck finding a small enough spot drill Have the guy drill the larger hole with the same geometry Guhring of the right size first 2 76 mm Guhring drills are worth the money, too bad the three fluters don't come any smaller than 3mm
  • CNC Machining | Guhring and Emuge endmills - Practical Machinist
    My largest contract customer in China signed on with Guhring as a single source vendor last year and they are quite satisfied I've been using and implementing both for a couple of decades now and for me Guhring takes the top for solid carbide hole making, Emugee, well, there is no competition for solid carbide milling
  • Guhring Mill Drill Huge Issues with Breakage and Tool Life
    Operation 1: Carbide Mill 2 0mm Guhring 16,000rpm at 190 mm min Operation 2: Carbide Drill 2 0mm Guhring 14,000rpm at 720mm min The material is SAE 1060 Rockwell C 26-36 Does anyone think this existing tool can be saved with feeds speeds or if I should pursue a different tooling supplier?
  • Anyone know what is happening with Guhrings website?
    As posted in the title, anyone know what's happening with Guhring com? It's been down for over a week, possibly longer since before I first tried to access it Been wanting to look up some tools from them, but their website won't load at all
  • CNC Machining | Three Flute Drills - Practical Machinist
    Hi Gang :) A few years back there was a "Rush" to sell Three Flute Drills These tools were touted to be used in solid material and not used as core drills I was doing pretty good with two flute drills so I never "picked up" any of them So now reflecting back on the three flute drill
  • CNC Machining | Drill Feed speed help - Practical Machinist
    I have a guhring 25mm 7x insert drill and I cannot get it to make a decent hole no matter what I do in 7075 The guhring salesman came back and we swapped the tool holder out for a nikken milling chuck I had This solved my problem I had thought We ran a test hole and all looked acceptable, but the machine wasn’t too happy doing it
