A More Productive Alternative to Helical Interpolation for High Volume Holemaking

The limitations of using milling tools to prepare holes for finishing become apparent as hole depth and volume increase. Enter the relatively simple and affordable twin cutter, which can solve this and virtually any other holemaking problem.

How to 3D Print Precision Drills

The new QTD insert drill from Mapal is manufactured by additive laser melting in diameters from 8 mm to 32.75 mm with a new steel tool body design that has spiral cooling channels not usually used for small diameters. The tool shank is machined conventionally and the drill is additive laser melted. (Photo courtesy of Mapal) (first view)
The days when precision tools and additive manufacturing strategies could not co-exist are history.

How to Thread Nickel-Based Alloys

This pipe tap uses Variable Helix Correction (VHC) technology that provides a specially ground relief geometry in the primary cutting zone, generating a smaller and tightly rolled chip formation.
Proper tooling selection is the key for optimal results in this demanding application.

The Whole Picture in Holemaking

The exchangeable-tip drill is a good choice for a large range of holes limited by tolerances down to IT9 and often deeper than five times the diameter. CoroDrill 870 represents the new generation of this type of drill and is a reliable choice for many operations and a number of different workpiece types. 
Today’s holemaking techniques need to be more efficient than ever to meet greater demands and closer tolerances. Ultimately, the tool — and its application — matter. For optimal success, it's time to see the whole picture.

How New Spindle Connection Maximizes Metal Removal

From Weakest Link to Machining Superstar: The new KM4X™ design from Kennametal can perform from low-speed/high torque to high-speed/low torque when milling, drilling, and turning a wide range of materials to get the absolute most out of your production equipment.

Gun Drilling in Tool Steel

Toolox 44 has a high hardness of 45 HRC and an excellent machinability thanks to its low carbon content and high homogenity. Mold and die makers sometimes have machining difficulties the first time they use this steel in long hole drilling of cooling channels that are required in the tool. 
Swedish steel maker SSAB explains how progress is being made on long hole drilling in wear resistant and harder mold and die steels as a way to avoid heat treating.

Self-Locking Taps Provide Holding Power That Lasts

Union Butterfield Self-locking Taps eliminate time intensive disassembly and assembly procedures and costly fasteners, chemical bonds, nylon plugs or other devices to maintain tightness. A 30 deg wedge lock on the female thread creates a continuous spiral contact along the entire thread length for improved holding power versus standard thread forms.
Union Butterfield self-locking taps from Dormer Pramet are ideal for working with aluminum or other lightweight soft materials used in transportation, medical or industrial applications.

Application Specific Thread Whirling Inserts in Less Than Three Weeks

Delivered in less than three weeks, special application specific inserts from GenSwiss are used with Utlilis thread whirling rings and attachments for popular threads such as standard metric, ANSI, and ISO Buttress style threads for most medical applications.
GenSwiss offers quick delivery of Utilis inserts for thread whirling that improves thread surface finish and can be utilized for threads smaller than 12 mm diameter in medical devices.

Online Customized Tooling in Minutes

Ideal for shops who may need a tool body that is longer, deeper, or shorter to miss a fixture, or who need special forms or a special geometry for difficult to machine materials, the online Insta-Quote system at Allied lets customers design, quote and order customized tooling in minutes, including special sizes, geometries, substrates, and coatings for tool bodies, blades and inserts. Also available are customized threadmills, reamers, and boring tools. For more complicated tools, application engineers can provide a quotation within two days, depending on the complexity of each request.
Using the Insta-Quote system from Allied Machine, shops can quickly design, draw and obtain a quote; instantly print it out with a PDF drawing; then confirm, process and deliver the order through a local distributor.
