Highly abrasive materials like cast iron, polymers, glass filled polycarbonates, and some cast aluminum are called “hard” materials for a reason. They’re hard to machine, hard on tool life and hard on production cycle times. How do you overcome the difficulties of making parts out of challenging raw stock? By using a tool that’s even tougher. Consider a change from steel taps to carbide taps.
The company is the world’s best customized solid carbide rod supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
While high speed steel (HSS) taps have a practical top limit of around 35-40 HRC before tool life becomes severely limited, carbide is often used in materials with hardness up to 65 HRC (the ones that chew up HSS in no time). With the appropriate style for the application, tool life of carbide can be 520 times that of HSS, with the added bonus of superior accuracy.
That’s easy. Our carbide taps are American made from high-quality C2 micro-grain carbide by highly skilled machinists on state-of-the-art equipment, and are backed by decades of experience from our support staff.
We offer carbide taps in UN and Metric sizes as well as straight and NPT/F Pipe and STI Standards. A wide range of styles and features are available, including straight flute, spiral flute, spiral point, and forming taps. For increased performance and life, we can customize tools with a full line of surface coatings such as TiN, TiCN, and TiALN.
Machining with carbide does come with some “do’s and don’t”. Hand tapping is generally not recommended. Rigid tapping and spot-on alignment are critical to avoid breakage. Not to worry, however. Modern CNC equipment is ideally suited for carbide applications.
Here’s some additional tips. Coolant holes through the taps are an option for flushing chips out of the holes on the most difficult materials like some of the tougher stainless steels and space-age alloys. Carbide STI (Screw Thread Insert) tapping of these materials has become commonplace in the aeronautical and aerospace industries.
Although initially more expensive than HSS taps, significant savings can be realized, especially in long-run jobs. Higher cutting speeds, greater tool life, and reduced downtime from fewer tooling changes translate into reduced machining costs.
An alternative to costly larger sizes is our line of CarbISert® Taps. Solid carbide cutting surfaces are bonded onto a high-speed steel body to provide the best of both worlds; durability of carbide with the “forgiveness” of a steel body and shank.
So, don’t let difficult materials give you a “hard” time. Contact us anytime and put our carbide taps to work for you.

Because of our exceptionally broad product listing of over 16,000 line items, our distributors seldom stock our tools unless they have a consistent demand for particular tools requiring same day delivery. HANNIBAL maintains a 99% line item order fill rate. We have a huge inventory of finished tools ready to meet your needs.
Normal procedure is to ship all distributor orders by UPS, unless requested otherwise. Our lost shipment insurance does not cover shipments sent “freight collect.” Buyer accepts the title of the goods at the shipment point and assumes all risk once the seller ships the product, including goods that are lost or damaged in transit. In the event of a damaged package, the damaged package must be saved and photographed by the receiver for UPS claim purposes submitted by the shipper.
The only description required to order a standard tool is the EDP number. However, as a cross-check, orders should include a brief description of the tool.
Over 20% of all standard tools ordered include requests for one or more modifications. On each page of this catalog is a list of the modifications most commonly requested. Just phone, fax, or e-mail us for an immediate quote. Modified tools are delivered promptly and are competitively priced.
HANNIBAL prides itself on the ability to solve end user tooling problems. We will suggest solutions including tool designs that have been used successfully to solve similar problems. Our proven applications engineering capability is reflected in the fact that some of the largest machine tool builders select HANNIBAL to design and produce the original cutting tools used in producing engines and transmissions.

30% of HANNIBAL’S sales are special order tools made to end user’s specifications and prints for the very demanding automotive, diesel engine, aircraft engine, aerospace, and construction equipment industries. To meet these stringent requirements, our engineers and tool makers work daily with exacting tolerances and procedures.
Our plants have consistently passed quality system inspections by key engineering, production and purchasing executives of our major tool users. HANNIBAL became ISO 9001 certified on August 18, 1999 and Ford Q101 certified in 1989. HANNIBAL’S manufacturing team produces the standard tools listed and the “specials” requested by our customers.
All our tools are manufactured to one or more of following specifications:
USCTI – United States Cutting Tool Institute
NAS – National Aerospace Standards
ISO – International Organization for Standardization
ASME/ANSI – American National Standards Institute, an affiliate of American Society of Mechanical Engineer
While price is always a consideration, the real measure of the tool’s value is its in-plant performance. HANNIBAL’S tool performance is proven where accurate records are kept, such as the aerospace and automotive industries. Here our tools earn “excellent” ratings … and that is why we are one of the fastest growing tool companies in the world.
HANNIBAL’S engineers, technicians, tool makers, sales & support staff are continuously focused on the goal of producing the world’s best carbide tipped tools. Our experienced tool makers sincerely want to do their best and, in fact, do their very best every day making every effort to manufacture tools that will meet your exacting needs.
