MSU-Manufactured Carbide End Mills

T-Slot End Mills

MSU manufactures the 4TE solid carbide T-slot end mill family in 36 confirmed catalog configurations. These four-flute tools are selected using the complete dimensions and clearance requirements of the T-shaped undercut.

Compare the configurations by cutter diameter, neck diameter, slot width, reach and shank. Send the exact 4TE code when known, or provide the part drawing, entry-slot condition and complete tool-clearance envelope.

Send the T-slot drawing, cutter and neck dimensions, entry condition and quantity for review or quotation.

Explore T-Slot End Mills

The MSU 4TE family consists of four-flute, solid carbide T-slot end mills. The current supplement contains 36 exact catalog codes.

A T-slot operation requires an entry path that allows the cutter head and neck to reach the undercut. The part drawing should show the finished feature, access slot and surrounding clearance. The MSU range covered here is limited to solid carbide 4TE tools; HSS, indexable and Woodruff keyseat cutters are separate product types.

Use Square End Mills to review the separate flat-end tool category when an entry or pre-slot operation is also required. Use Carbide End Mills to compare the complete MSU end-mill range.

Compare Series and Configurations

The 4TE range contains one family. Compare cutter diameter, neck diameter, slot width, reach and shank to select a configuration.

MSU 4TE T-slot end mill configurations compared by cutter diameter, neck diameter, slot width, reach and shank with the information to provide and its review purpose.
Comparison input What to provide Review purpose
Cutter diameter Required cutter-head diameter and available radial clearance Matches the cutter envelope to the part drawing
Neck diameter Required neck clearance and minimum supported neck condition Checks access through the entry slot and clearance inside the feature
Slot width Finished drawing dimension and tolerance Identifies the required cutting-width condition without inferring it from another field
Reach Distance from the reference face to the cutting location Checks whether the tool can access the undercut within the setup envelope
Shank Shank diameter and holder requirement Checks the tool-to-holder interface requested for review

Also confirm flute length, overall length, workpiece material, operation, machine, holder, coolant and quantity. MSU checks the catalog dimensions together with the finished slot drawing before confirming a configuration.

Continue to the drawing, entry path and clearance information needed for selection.

  • Entry or pre-slot dimensions and confirmation that the cutter can enter the feature.
  • Required cutter diameter, neck diameter, reach, shank, flute length and overall length.
  • Workpiece material, grade, hardness and surface condition when known.
  • Operation, toolpath, engagement, machine, holder, overhang, workholding and coolant method.
  • Quantity, destination country and target date.

Selection principle

Review the complete access envelope

The neck and cutter head must be reviewed together with the entry slot and machine clearance. Do not select a 4TE configuration from finished slot width alone.

Outside the catalog range

Custom Cutting Tools

If the required geometry, reach, shank or clearance condition is outside the current catalog range, submit the drawing for feasibility review.

Send the part drawing and access envelope so the 4TE configuration can be checked against the application.
