Nes tools automatically reform the thread pitch of most typical internal or external applications with a high-speed steel blade by following the existing thread pitch.
Yes, it has the same form cutting ability due to the existing thread. The advantage is that the chips can be evacuated ahead of the tool.
No, the reduced cutting forces and the small amount of material being removed will not generate the heat or distortion. A light oil or fluid adding lubricity will enhance the cut rate and improve the finish when dealing with ferrous metals and alloys. The lubricity will extend the life of the cutting blade. Some non-ferrous materials will have an improved finish and better cut rate without a fluid.
No, the tool requires a root or partial thread angle in guiding the tool blade throughout the profile.
Yes, it uses the root and angle of the thread to establish the diameter and restore the 60-degree crest of the thread. The Nes tool does either right- or left-handed threads. You control the rotation and direction of the cutting tool.
Yes, we offer cutting tool blades in an orange color-code with a 55-degree angle to form British Standard Whitworth (BSW), British Standard Fine Pitch (BSF) and British Standard Parallel-Pipe (BSP) thread forms.
No, Nes doesn't offer anything for Acme threads. It offers 55/60 degree only.
The tool can save maintenance, mechanical, plumbing and construction workers from disassembling and reassembling a unit. It takes the quest work out of measuring the thread size and pitch. Nes tools are lightweight, vestal, compact and durable and useful in confined environments or workspaces.
The leading edge of the thread is prone to wear at the start of engagement. Misalignment and wear will cause further crest damage. The Nes tool chases the existing thread angle and strengthens the crest of internal and external threads. Therefore using two tools from Nes will qualify the crest and pitch angle of the mating parts to insure proper assembly and torque strength.
No, a tap can't pick up the original path of the initial cutting tool. Nes maintains the original centerline of the internal thread by following the existing groove.
No, because threading dies have a tendency to nick the crest of the original threads. Wear or being too out of round prevents the die from picking up the original plane of the groove. The Nes tool uses the original groove to maintain concentricity.
Yes, provided we have a section of thread that is not damaged from the chemical or physical process. The Nes tool can remove the scale or rust and improve the surface integrity and finish.
Yes, if you have used a worn out tap or die the Nes can make up for wear by removing enough material to get you to the pitch diameter and eliminate any interference issues.
Nes tools are designed for recutting threads that were flattened or compressed. Nes has to be mounted on an undamaged thread, 20mm is sufficient for the first blade to meet the damaged area and to perform the repair. However if you don't have sufficient undamaged thread it is suggested to mount Nes on a clear side of the thread— while the damaged area is in between the blades. (In other words: let us say that the thread was horizontal while it was hit by a hammer on the upper side of the thread, in that case we recommend mounting the Nes while the blades engage the opposite side of the thread.) In that case part of the damage will be repaired by the second blade only. At least 20mm are needed after the damaged area to repair with both blades on the thread along the whole reparation. It is also possible to repair with just one blade on the thread but more attention should be taken. Nes tools do not cut new thread. With severe damages there is a possibility of cross threading.
Nes offers an attachment known as a 3 Keyway Skip Accessory. The tool allows the blade to skip over the slots on larger external threads and shaft that are designed for a key or tab washer.
Yes, but we offer two types of replacement blades. One in 60 degrees for Metric, National Fine or National Course, and National Pipe Threads and another in 55 degrees for BSW, BSF and BSP (British Standards) which are color-coded in orange.
The Nes tools are designed to reach inside threads 1" (25mm) deep to restore most damaged areas.
Anyone involved with both inches and metric mechanical issues and repairs on ISO, UNC, UNF, NPT, BSW, BSF, BSP standards.
