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.

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.

PCD Inserts for Drilling in CFRP Used in Aircraft

Polycrystalline Diamond T-A Drill inserts feature a replaceable tip design, allowing users to replace only the tip of the tool when it has worn out, unlike competing products that require the entire tool to be removed and replaced. This saves costs for users in the long run by reducing the cost of replacement tools. The inserts feature the standard T-A Drill insert with PCD wafers installed at the insert’s cutting edge.
Polycrystalline Diamond T-A Drill inserts from Allied Machine can withstand strong and highly abrasive materials like CFRP-titanium stacks, aluminum, titanium, copper, magnesium, fiberglass, and chipboard used in the aerospace and automotive applications.

Unparalleled Cutting Speeds and Tool Life in Gray Cast Iron, Ductile Iron, Forged Steel

“Speed-Drill R4” geometry uses a new corner radius design that is tangential to the drill point but non-tangential to the diameter to address challenging, high production drilling applications. Monaghan offers single tool operations for close tolerance bores with complete project management for all solid carbide tools that are ideal for ferrous and non-ferrous applications.
Monaghan Tooling offers “Speed-Drill R4” geometry in solid carbide round tools from MK Tools that effectively drills all popular materials used in automotive engine and chassis components.
