The Whip Guide Company



Hyper Tool has been producing state of the art gundrills since 1946. Our patented products have contributed significantly to the industry as a whole. We have developed a wealth of technical knowledge and experience over the past 50 years which we are glad to share with our customers. Please feel free to contact us with your gundrilling questions or problems...a simple phone call or e-mail is all it takes.

We hope this site will be useful to you. We have included information about our products, as well as useful information on all aspects of gundrilling. This growing library of information is located in the Technical Help section of our website. Please check back often as it is being continuously updated.

Hyper Tool and The Whip Guide Company share common ownership and are located in the same facility. This website includes complete information on the products of both companies.

Why Choose Hyper Tool?

What’s different about Hyper Tool is that we are more than just skilled machinists and conscientious customer service people. We are engineers who understand the mechanics of metal cutting and the fundamentals of good tool design. We have learned, through theory and testing, how and why gundrills work, and what can be done to optimize their performance. Our state-of-the-art R&D laboratory, unique to the gundrilling industry, has enabled us to disprove many historical myths and misconceptions, while in the process of making a host of significant new discoveries. We have developed a library of mathematical models describing the interrelationships between each of the many parameters in the design of a gundrill.

In our 50-plus year history, Hyper Tool has contributed more to the gundrilling industry than everyone else combined. For example, we patented the Gizmo® Gundrill Whip Guide in 1965. This breakthrough allowed significantly higher rpm with a commensurate increase in penetration rates. In 1971 we patented the Kidney Hole® tip design, which allows for up to 40% greater coolant flow. Our Threadlock Detachable Head Gundrill virtually eliminated tool change downtime, and our Universal Gundrill Sharpening Fixture made it possible for both large and small users to quickly, accurately, and economically reproduce their point grinds. It is the only manual fixture on the market that will reproduce both the “cam-relief” (American standard) and the “facet-grind” (European standard) point geometries.

As it turned out, all the above Hyper Tool inventions have been imitated by our competitors, which some would consider being the “highest form of flattery.” So we are no longer seeking patents for the knowledge base we have been building, but instead, continuously applying this knowledge to the design of gundrills for our growing customer base. For example, we have successfully replaced the fragile and expensive two-flute gundrill with much less expensive, application-specific single flute gundrills, for both aluminum and cast iron applications; not only at the same or better penetration rates, but yielding straighter holes with better surface finish.

Carbide grade, coolant hole configuration, tool design and drilling parameters all interrelate and must be determined together, in the context of the customer’s workplace. The workpiece material, the drilling machine, the coolant system and even the operator skill are the workplace variables that need to be understood before the operation can be fully optimized.

As professionals, Hyper Tool invites its customers to complete a questionnaire (attached) before we attempt to produce an Application-Specific gundrill for them. (If your doctor doesn’t ask “where it hurts” before giving you a prescription, you probably should find another doctor.)

Hyper Tool also produces state-of-the-art Standard Gundrills because the market demands it. The insidious problem with any standard, off-the-shelf gundrill is that it does, generally, produce holes. Unfortunately, today’s “if it ain’t broke, don’t fix it” mentality causes many users to settle for a great deal less performance than might otherwise be possible. This problem is exacerbated by the “need it now” demands of today’s manufacturing environment.
