Taps & Threading Tools

GN 742.5 Fluid/Fill Drain Plugs, GN 738.5 magnetic plugs and GN 7440 fluid sight glasses are made of AISI 316L (A4) stainless steel. Winco offers the premium sight glass in standard sizes from M16 to M42 and G⅜ to G1¼. Other thread diameters are available on request. Naturally, the same applies to the threaded plugs GN 742.5 and GN 738.5.n

Joe Magee, Vargus USA's product manager for threading and thread milling, offers an overview of the company's newest products, including the Mach TT threading tools for lay down and thread milling.

SpeedTaps are meant to be driven by an impact gun along with an impact socket, for through-hole applications allowing the user to quickly move the tap through the material as the impact gun does its work. The taps are designed with an aggressive starting pitch to catch and start cutting faster than traditional taps.

The special profile of EMUGE SELF-LOCK threads allows an even distribution of stress over the entire thread length, eliminating slippage. Compared with standard threads, EMUGE SELF-LOCK internal threads show constant, maximum holding power under dynamic stress. Functions remain in good operation even with repeated loosening and re-tightening of the thread connection. The locking effect is caused by the ramp-shaped surface integrated into the thread profile,

Broken taps usually come from a combination of hole prep, chip control, alignment, and parameter problems. This guide covers practical ways to reduce tap failure.

The added anti-vibration boring bars with C6 PCS machine side connection are suitable for up to 9xD boring depths, allowing direct assembly on the machine spindle or turret without the need for adapters. The boring bars can also minimize chatter as an integrated vibration damper suppresses unwanted vibrations during machining.

The TC430 Supreme thread former, specialized for ISO P materials, is for blind-hole and through-hole threads up to 3.5 x DN. Multiple coolant configurations are offered to best optimize performance—axial or radial coolant, with or without lubrication grooves. This HSS-E-PM thread former with AlCrN or TiN coating is available for both metric and metric fine threads. Grade designations are WW60AD andWW60EL.

The TC420 Supreme includes one configuration with chamfer form E, (M5–M16) for blind-hole threads up to 3.5 × DN, which uses an innovative combination of chamfer form E with axial internal coolant and without lubrication grooves. This new combination also improves the lubrication and, at the same time, reduces the torque by up to 30% – with a corresponding extension of tool life.

As the name suggests, cutting taps produce threads by progressively cutting away the space between threads into which the fastener's external threads will fit. Forming taps, by contrast, remove no material. Instead, they move or displace material inside the hole to build up the threads and dig into the grooves.

Most importantly, they are punching square, rectangular and round openings not only in control cabinet doors and housings, but also in mounting plates, terminal boxes, cable ducts or cable routing plates. The three variants AP 600, AP 400 and AP 250 are suitable for processing switch cabinets or switch cabinet doors with a throat depth up to 600 mm, 400 mm, or 250 mm. Depending on the model, the punches can be used on sheet steel with a thickness between 2.5 mm and 3.0 mm. Stainless steel can be processed up to a thickness of 2.0 mm. In addition, the machines from the AP line are punching plastic up to a thickness of 4.0 mm.

The CoroTap T200 and T300 are optimized for ISO P1 and P2 steel workpiece materials, making them suitable for machining components in the automotive and general engineering industries. This includes crank shafts, steering knuckles, and general engineering components such as housings and flanges. Both tools are suitable for mass production.

The FSH combines the latest in substrate and coatings with multiple flutes and the highly effective left-hand helix design to achieve both better performance and longer tool life in today's hard-to-machine materials. Manufacturers who have previously attempted to use taps in small-hole threading understand that, especially in heat- resistant materials, breakage is a frequent occurrence.
