Double-Sided Button Inserts and Cutter Bodies:
14Pages

The EDGE² DTB roughing series features double-sided button inserts and super-tough cutter bodies for premium performance across a wide range of roughing applications. Double-sided DTB inserts provide twice the number of usable edges as a normal, single-sided insert. From mold cavity, core and complex part contour roughing to helical interpolation, pocketing, semi-finishing and face milling, the DTB series was designed to help you maximize your efficiencies in your most challenging roughing applications. TOROID / BUTTON CUTTERS Double-Sided Button Inserts and Cutter Bodies: Twice the Metal Removal – Twice the Value DTB Toroid Roughing Series Single-Sided Double-Sided • utstanding insert life for roughing applications – significantly outlasts single-sided button inserts, as well as O competitors’ double-sided offerings • Thicker carbide insert provides better heat and stress absorption • mooth cutting action, with available geometries suitable for cutting virtually all materials (except bar-stock S aluminum and plastics) • nti-rotation raised dimples for securely and consistently seating insert in cutter body when indexing A • ecessed mounting face creates unobstructed chip flow for reduced stress and heat R • Capable of metal removal rates approaching high-feed, but with better reliability DTB Series Cutter Bodies • Super-tough, high-shock tool steel • Fully thru- and case-hardened bodies for optimum strength and longevity • High accuracy/centrality for minimal runout, providing best finishes and tool life • nti-rotation recessed dimples correspond with raised insert dimples for secure, consistent seating and indexing A • hru-coolant standard in many bodies for optimum air blast or high-pressure coolant use T

TOROID / BUTTON CUTTERS DTB Double-Sided Button Inserts Round inserts have a strong cutting (old versionsmaking them an excellent choice for many edge, for comparison) applications, including: • old cavity and core roughing M • Roughing of complex part contours • elical interpolation (larger diameter hole making) H • Face milling “D” INSERTS Positive cutting geometry designed to reduce cutting forces and heat. Suitable for most materials except hardened steel. “T” INSERTS Reinforced cutting edge for steels, irons and hard milling. Fancier “cutaway” style Fancier “cutaway” style DTB Grade...

Your DTB series tool has hemispherical dimples designed to provide anti-rotation support, as well as help maintain a minimum of 6 indexes per insert side (12 indexes total per insert). It is important that the insert be loaded correctly – with the raised dimples on the insert seating down into the recessed dimples in the cutter body pocket. See the diagram below.

TOROID / BUTTON CUTTERS DTB | DOUBLE-SIDED Application Information Recommendations • ool is most appropriate for “Z-level” roughing; ramp to Depth of Cut T (DOC) and clear entire level. • Plunging is not recommended with DTB series cutters. Ramping (up to 2° max.) is recommended. • ry to maintain at least 75% of the cutter diameter on the T workpiece whenever possible. Hanging a cutter off to the side of your work is detrimental to tool life and performance. • idth of Cut (WOC) should be 60-75% of cutter diameter W whenever possible, creating a “scalloping” effect (end mills only) between...

Your DTB series inserts utilize chip-thinning for optimum performance. Chip-thinning is the process in which the actual chip thickness created by a cut is less than the FPT at which the tool is programmed. See the chart below to see the chip-thinning factor for various depths of cut. For a correct chip thickness, multiply the FPT (from page 55) by the chip thinning factor below. This will give you an accurate feed and optimize your performance. This diagram (left) shows the varying chip thickness when feeding .010” feed per tooth (FPT) at different depths of cut (DOC) with a 12mm diameter...

TOROID / BUTTON CUTTERS DTB | DOUBLE-SIDED Hole Diameter Calculation Helical Interpolation for Larger-Diameter Hole Making Shell Mill Part Number Formulas: Minimum Hole Dia.: (Tool Dia. x 2) - (1.5 x Insert Dia.) Maximum Hole Dia.*: Tool Dia. x 2 * ot generally recommended. At this diameter, N the center tip is at its maximum. It is suggested that you stay slightly under this number. Larger diameter hole making can be quick and easy when a DTB Series Cutter is used in combination with helical interpolation. This technique resembles thread milling in that all three axes (X, Y and Z) are in...
