Description

The CHICAGO-LATROBE 69884 is a taper-length drill bit set consisting of 15 pieces with sizes ranging from 1/16 inch to 1/2 inch in fractional inch measurements. These high speed steel bits with straight shank and two-flute spiral design are intended for drilling operations in cast iron and steel materials. The drill bits have a conventional 118-degree point angle, a black oxide finish, and are rated for right-hand cutting; maximum drilling depth varies by bit size class within the specified depth-to-diameter ratio (4xD).

Key Features:

  • Set includes 15 drill bits with sizes incrementally included from 1/16" to 1/2" by 32nds.
  • High speed steel material with general-purpose grade suitable for machining cast iron and steel (ISO codes K, P).
  • Maximum depth of cut is based on the specified taper-length class and depth-to-diameter ratio (4xD).
  • Two-flute spiral design with a helix angle of 28 degrees for chip evacuation.
  • Black oxide finish applied to the cutting surface.
  • Drill diameter tolerance ranges from +0.0000 in / -0.0005 in to +0.0000 in / -0.0010 in.
  • Right-hand thread direction and does not include coolant through the flutes; use external coolant when required for the drilling operation.
