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.

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.

Coolant-Through Tooling

The Walter Turn Precision Coolant system directs coolant through the insert clamp and along the flank face of the insert for a 30 percent to 150 percent tool life increase when machining stainless materials, high temperature alloys and steels. Beginning at pressures as low as 150 psi, the system targets coolant precisely at the cutting edge for greater lubrication, cooler inserts and improved chip control.  
By targeting the coolant stream as close to right place in the cutting zone as possible, coolant-through tooling systems can bring improvements that range from higher cutting speeds to better surface finish by effectively controlling chips and helping to optimize tool life and increase production. Here are some of the latest systems to consider.

Cutting Wheel for Heavy Duty Steel and Stainless Steel Jobs

The 1/16 in thick ZIP+ XTRA cutting wheel from Walter Surface Technologies easily cuts through steel or stainless steel in heavy duty applications with an exclusive, patented rib design that reduces friction on the surface for faster and cooler cutting.
