Complete Guide to Allied Machine Cutting Tools: History, Product Lines & Grade Selection
About Allied Machine
Allied Machine & Engineering Corp. is an American cutting tool manufacturer specializing in holemaking and finishing solutions. Founded in 1940 and headquartered in Dover, Ohio, USA, Allied Machine has built a strong reputation as a niche leader in indexable drilling and boring technology. The company is a privately held family business that has grown from a local tool and die shop into a global supplier serving automotive, aerospace, energy, and general manufacturing industries. Allied Machine operates manufacturing facilities in Dover, Ohio, and maintains distribution in over 40 countries. The company is particularly renowned for its GEN3SYS® indexable drill system and the Wohlhaupter boring system (acquired from the German company). With 3,769 products on Hooguu, Allied Machine offers specialized holemaking solutions that complement the broader cutting tool offerings of other brands.
Allied Machine Product Lines
Turning Inserts
Allied Machine’s turning products focus primarily on boring operations rather than general turning. The Wohlhaupter boring head system is the company’s flagship turning product, featuring fine-boring heads capable of achieving IT6 bore tolerances with surface finishes below Ra 0.8 um. The Wohlhaupter system includes coarse and fine adjustment mechanisms with micrometer-precision diameter control. Allied Machine also offers BoreMax rough boring heads for rapid material removal in bore-enlarging operations, and precision boring bars with anti-vibration dampening for long-overhang internal turning.
Milling Cutters
Allied Machine offers a focused milling range that complements its drilling specialty. The AccuPort432® port mill is designed specifically for machining hydraulic and pneumatic port connections (SAE and ISO port sizes). The T-A® Mill indexable milling cutter series provides versatile face and shoulder milling for general-purpose applications. Allied Machine also offers spot-facing and counterboring cutters for hole-finishing operations that complement their drilling product line.
Drilling Tools
This is Allied Machine’s core specialty and primary market differentiator. The GEN3SYS® indexable drill system is the company’s flagship product, featuring third-generation self-centering geometry with replaceable carbide tips. Available in 1xD, 3xD, 5xD, and 8xD depth-to-diameter ratios with diameters from 11 to 100 mm. GEN3SYS® produces holes to IT8-IT9 tolerance with excellent straightness. The T-A® (T-A Pro) drill system is an earlier-generation platform still widely used for general-purpose indexable drilling. The AccuDrill series provides high-precision solid carbide drills with through-coolant for aerospace and medical applications. Allied Machine’s HP Drill (High Performance) line handles extreme applications in hardened steels and exotic alloys.
Grooving & Threading
Allied Machine offers specialized grooving tools for port machining and groove-finishing operations. The Port Tool series provides ORB (O-ring boss) port preparation tools for hydraulic fittings. While Allied Machine does not focus on general-purpose grooving or threading, their port tools and counterboring systems serve important niche applications in fluid power and automotive manufacturing.
