Gold TiN coated HSS jobber drill bit split point .4130 size Z

Chicago-Latrobe

Chicago-Latrobe 41796 135° Jobber Drill Bit Z .4130 HSS TiN Split Point

SKU CH-PC9T-BAFM8

A 135° split-point jobber drill bit in high-speed steel with TiN coating, sized Z (.4130 decimal)

  • Product typeDrill Bits
  • 135° split point starts on contact without wandering
  • TiN coating reduces friction for longer cutting life
  • High-speed steel handles heat in tough materials
  • Letter Z size equals .4130 decimal for precise fits
  • Jobber length gives standard reach for general drilling

Industrial drilling accessory

The Chicago-Latrobe 41796 is a jobber-length drill bit sized to Z with a decimal equivalent of .4130. It targets maintenance technicians and metal fabrication shops that need a single high-speed steel cutter for general-purpose holemaking.

Heat and wear characteristics

High-speed steel construction with a titanium nitride coating reduces friction and resists heat buildup during extended drilling cycles. The 135-degree split point centres the bit without a pilot hole, lowering thrust force and cutting noise in handheld or press operations.

Coating and geometry benefits

The TiN surface treatment extends edge life in mild steel, aluminium and plastic compared with uncoated HSS. Split-point geometry eliminates walk on curved surfaces, while the jobber flute length clears chips efficiently without requiring through-coolant delivery.

Questions about this item

How do I install the 41796 drill bit in my drill chuck, and what step do people often miss?

Open the chuck fully, insert the shank of the 41796 bit straight and deep, then tighten securely; the step many miss is verifying the bit runs true before drilling.

What maintenance or replacement will the 41796 bit need over time?

The 41796 high-speed steel bit with TiN coating will eventually dull; resharpen the 135-degree split point or replace the bit when cutting performance drops.

What limit appears first on the 41796 bit during sustained drilling?

Heat buildup at the 135-degree split point is the first limit; the non-coolant-through design means you must pause to let the .4130 bit cool.
