Improved Chip Removal With Boring Bar Line, Offset Adapter
Together with A2201's larger offset dimensions, the internal coolant delivery of the A3001 boring bar optimizes chip removal, adding to its superior surface finishes. Walter says it provides fast and productive counterboring and internal profiling of parts.

Walter has expanded its Accure∙tec anti-vibration boring bar line with the addition of the A3001 boring bar with the A2201 intermediate offset adapter for larger-diameter bores.
The standard A2201 is an offset adaptor for reduced radial forces and greater stability; it reportedly provides more space between the boring bar and the bore wall for improved chip removal with very deep bores. With the A3001 and the A2201, Walter has increased boring bar diameters to 2.5"-4" and 60-100 mm. The Accure∙tec A3001, with its patented vibration dampening system, is said to excel at length/diameter ratios beyond 6 × D up to 10 × D.
According to Walter, users of the Accure∙tec A3001 or A3000 boring bars will not have to worry about time-consuming “fine-tuning” of the dampening function, as its patented anti-vibration feature is preset at the factory and the tool is ready for quick application. The new tool is available with both negative and positive inserts.
With the A3001, Walter offers Capto C6, C8 and HSK-T 100 connections, and the compact QuadFit precision (±0.002 mm) quick-change exchangeable heads are said to decrease downtime and boost versatility. Together with the A2201's larger offset dimensions, the internal coolant delivery of the A3001 boring bar optimizes chip removal, adding to its superior surface finishes. It provides for fast and productive counterboring and internal profiling of parts in industries such as aerospace, oil and gas and general metalworking. Walter says this product addition enhances the already existing product line of A3000 anti-vibration boring bars, which do not require the A2201 intermediate adaptors and cover the diameter range of 1"-2" and 25-50 mm.
