Originally published on Endurance Carbide NEWS To extend the life of your tooling and improve the quality of your product, you need precision wear parts built to withstand the rigors of your metal stamping application. At Endurance Carbide, they manufacture all of their punches from tungsten carbide.
2. Carbide punches have a surprisingly long lifespan.
Compared to steel, tungsten carbide lasts for a greater span of time. As a result, carbide punches need to be replaced less frequently than their steel counterparts. So while steel might seem like the most cost-effective choice, the need for constant replacements offsets any upfront savings and makes them the more expensive choice in the long run. 3. Carbide punches boost productivity. Every time a replacement is needed, not only do your maintenance costs go up, but productivity takes a serious hit. In order to improve productivity – which equates to increased profits – you need reliable wear parts that can hold up to the demands of your precision machinery. That’s where tungsten carbide punches come in. Because of their rigidity and unparalleled strength, wear parts made from carbide have a long lifespan, effectively minimizing downtime, and as a result, the time spent servicing your equipment.

Re-tipping or Re-sharpening Carbide Tipped Milling Cutters A Cost Effective Option to Buying New Tools Cutting Tools are not exactly cheap. One of the best ways to get extended life out of your milling cutters is to have them re-tipped or re-sharpened. This can usually be done at a fraction of the cost of the original cutter and is much quicker than making a new cutter from scratch. It can bring the cutter back to its original or acceptable specs. Lexington Cutter re-tips and re-sharpens a lot of cutters including the cutters we use in our shop to make the tools we sell.
Re-sharpening is exactly what the name implies. Re-sharpening the cutting edges to remove imperfections generated during the cutters normal use. Care must be taken to minimize the amount of stock removal so not to undersize the cutter beyond an acceptable range and to allow for a greater number of future re-sharpenings. Depending on the condition of the cutters re-sharpening may include sharpening the OD, sharpening the width, or face lapping. Re-tipping involves taking the old pieces of carbide off, brazing on new pieces of carbide, and re-sharpening. This typically brings the cutter back to its original specs. Re-sharpening is slightly cheaper than re-tipping as there is less work involved and no carbide costs. In order to be re-tipped or re-sharpened the existing cutters need to be in good shape. The steel backing behind the teeth has to be in-tact. The tools cannot be bent. The hub on arbor hole style tools shouldn’t be too beat up (although this can sometimes be fixed by regrinding the hub). The arbor hole should not be damaged excessively. As long as the operator is conscious of the fact that the cutters are going to be re-tipped or re-sharpened keeping the tools in decent shape is not a problem. It is important to have enough existing cutters on-hand so the tools can be switched out before being run beyond the point of repair. Too often we receive tools that are beyond the point of repair. But, we also have several customers on a re-tipping program that are very good about keeping their cutters in a repairable condition and regularly send them back to us for this service. One advantage to using carbide tipped cutters over solid carbide or high speed steel cutters is the fact that they can be re-tipped. Once solid carbide or HSS cutters have worn down beyond an acceptable range, that is the end of their life. Carbide tipped cutters can be re-tipped as many as 3 or 4 times greatly extending the tool life beyond that of solid carbide or HSS cutters. Super Tool can typically turn around re-tipped or re-sharpened cutters in 1-2 weeks which is much shorter than making them from scratch. We can re-tip or re-sharpen special cutters and we can re-tip or re-sharpen standard cutters. Re-tipping does have its limitations. In order to remove the carbide tips the teeth have to be heated up. To put on new carbide the teeth are heated again. This constant heating of the steel eventually changes the molecular structure of the steel making it weaker. This is liable to happen after 4 or more re-tips which is why we limit the number of re-tips to 3 or 4. Call: (440) 463-3970 or email: dmb@brownesales for more information on re-tipping or re-sharpening your carbide tipped cutters The national standard for NPT (National Pipe Taper) taper pipe threads is ASME B1.20.1, the current edition has a date of 2013.
This standard contains product detail values and their calculation formulas as well as conformance requirements. It also contains gage design details used to evaluate only some of the conformance requirements. Yes, you read that correctly, used to evaluate only some of the conformance requirements!

If not, you definitely should because it performs exceptionally in high-speed machining and full diameter milling, as well as dominates in stainless steels, super alloys, and titanium.
Its tool versatility results in higher productivity, less tool changes, and longer tool life. Fullerton's Fury works well in both roughing and finishing applications and produces excellent surface finishes, while its FC-20 coating significantly reduces operating cutting temperatures. We have included a case study on how our 3500 Fury end mill generated a 78% reduction in time per part for our customer, while also reducing the cost per part by 86%, and generating over $20,500 in cost savings.
