Davis by Cline Tool

Davis Tool

The Davis Block Type Boring Tool System

Increases productivity and reduces tooling costs for vertical and horizontal boring machines and machining centers.

  • Up to 50% lower initial cost: Just five standard Davis bars handle all boring jobs from 1″ through 12.5″ diameter
  • Cut three times faster: Two cutters cut faster than one. Feeds with Davis two-cutter blocks are up to three times faster than with single point tools
  • Greater range of operations per bar: Seven types of interchangeable, cutter blocks enable one Davis bar to handle multiple machining operations
  • Balanced chip load promotes accuracy: Davis system assures accurate, round taper free bores every time. Chip load is balanced between the cutters. Opposed cutting action minimizes the effect of tool wear and bar deflection
  • Presetting holds tolerances of +.0005″: Adjustable tooling provides a full presetting of both radial and axial accuracies, with tolerances of +.0005″ on diameters easily held with normal care

  • Type STL & ST: Two-cutter and roughing & semi-finish blocks. Standard throwaway inserts, excellent choice for fast removal of excess stock in rough bores.
  • Type AT: Two-cutter semi-finish and finishing block. Adjustable throwaway inserts lock and adjust radially. Production boring with maximum economy.
  • Type E: Two-cutter rough and finishing block. Expandable cutters adjust to compensate for wear. Regrinding for both diameter and depth for complete positive control of machining accuracy.
  • Type MST: All-purpose single-cutter block. Micrometer adjustable in increments of .001″ radially over a wide range of bore diameters Best used for short runs and one-of-a-kind applications.
  • Type STC: Single-cutter chamfering block. Blocks with throwaway insert for 45° chamfering applications.
  • Solid Block: All-purpose boring and facing tool. Manufactured from super high speed steel, or with brazed carbide, for machining large faces or chamfering holes.
