Drilling Machines

Drilling flat-bottom holes is a challenge. So is drilling on inclined or curved surfaces, drilling into cross holes, drilling stacked plates, and drilling into cross holes, stacked plates and castings and other rough surfaces. Not anymore. Leveraging the success of its KenTIP FS modular drill, Kennametal has developed a unique insert geometry (FEG) that streamlines many of these types of applications and simplifies the drilling of counterbores and pilot holes as well.

Dream Drills Pro tools are made with micrograin carbide for exceptional core strength and longer tool life. They also feature YG-1’s unique, wave-shaped cutting edge to reduce cutting forces, and an advanced, wide-flute design optimized for faster, reliable chip evacuation. A self-centering 140° point angle reduces torque and extends tool life. 

The T-A Pro drill combines material-specific insert geometries, a redesigned drill body and a proprietary coolant-through system to allow penetration rates which run at speeds nearly 30% faster than other high performance drills on the market. Coolant outlets are designed to direct maximum flow to the cutting edge providing quick heat extraction where it is most critical - even at significantly higher speeds.

With five models built from two frame sizes, the UNE Series can drill hole diameters from 1.4 mm to 40 mm and depths up to 3,000 mm. The compact frame construction saves valuable floor space as well. Each machine can fit in close proximity to a shop’s existing machining center, lathe or Swiss-style machine for efficient part-processing strategies. Built with quick and easy set-up in mind, the machines are also small enough to be relocated when necessary. For added flexibility to grow with future production needs, all UNE models are robot-ready, allowing shops to add a robot whenever it fits into their budget and production schedule.

New to this next generation of Red Helix™ Drill Bits are two features: a Quad Edge™ Tip and Enhanced Tapered Web™. The Quad Edge™ Tip delivers a longer life with a precision start and four cutting edges to stay sharper longer. The drill bits’ Enhanced Tapered Web™ acts as an internal backbone and strengthens the bit to reduce premature breakage; a common user frustration.

With the special flute geometry, the chips (swarf) are evacuated effectively. This means that hole depths of up to 12 x Dc can be easily achieved. Oil or emulsion can both be used as a coolant with these drills. For deeper holes beyond 8 x Dc, Walter has also introduced a corresponding line of pilot micro drills, the DB131. 

The new version of the solid carbide plunge mill is based on the same technology as the short version, transferred directly to the new one. Now it is possible to plunge perpendicularly into the material and reach the maximum milling depth of 5 x d in a few steps. Despite its length, the milling cutter is extremely stable and at the same time impresses with its cutting speeds, chip removal rates as well as a long tool life and surface quality, all this from a milling diameter of one millimeter (.039”). 

FH3125 is a new grade specifically developed to enhance the guide pad’s wear resistance in machining various materials. The dedicated carbide substrate of the grade is designed to reduce guide pad breakage, providing long and predictable tool life in deep hole processes. The corners of both ends of the guide pad are designed to allow smooth entry into the guide bushing or pilot hole to control vibration impact and further decrease the risk of rupture.

The latest additions include inserts with 0.8 mm (.032″) nose radius in versatile AH725 grade. 0.8 mm nose radius will provide the cutting edge with strength, preventing edge fracture for predictable tool life. In addition, AH725 enhances the insert’s wear resistance during machining of various materials, ensuring high precision and boosts productivity. 

This 32mm capacity machine (with the capability to increase to 38mm) has a new design that helps improve productivity and operating convenience.  The standard 12 cutting axes includes a B axis for angular drilling and contour milling.  In addition, the 10 station turret with half index capability provides 20 positions.
