A-Tap – new product that showcases OSG’s 75 years

The A-Tap is an all-purpose tap series designed to simplify tool management and to excel in a wide variety of materials and applications. The A-Tap is made from powdered metal HSS and has OSG’s patented V coating to achieve excellent wear resistance. The spiral flute series has adopted a variable helix flute design, which encourages stable chip evacuation and reduces cutting forces. The spiral point series has unique geometry that enables greater chip control that can help produce tightly compacted chips for easy ejection from the hole.

The developer of the A-Tap®, Takayuki Nakajima, explains the concept behind this series in detail – “OSG turned 75 in 2013. In celebration of our 75th anniversary, I developed the A-Tap® as the first of a number of new products to help us advance toward OSG’s 100th anniversary. OSG offers a number of all-purpose tooling such as the EX series, TIN series, V series, and now the A-Tap series. The A-Tap is one of our greatest innovations in the last 20 years since the V series. The biggest advantage of the new A-Tap® series is its versatility. It is engineered to excel in any material, any application, anytime!”


A-Tap® ‘s inspiration
“After a careful analysis of our customers’ feedback on common tapping problems, we have discovered that the top three tapping issues include “chipping and breakage,” “dimensional errors,” and “galling.” All of the mentioned problems are caused by the inability to evacuate chips effectively, creating conditions such as bird nesting. To avoid these problems, customers often have to compromise efficiency and would run their taps at much slower speeds, even when their machining centers were capable of higher performance. With this in mind, our goal was clear. We needed to develop a tap with zero evacuation trouble so as to allow our customers to achieve maximum performance based on their machining center’s capability.”
