Chicago-latrobe 53901 Jobber Drill Bit 1/8 Inch Hss Tin

Product Description

The CHICAGO-LATROBE 53901 is a jobber-length drill bit designed for production and maintenance drilling in steel alloy and similarly hard materials. Built from heavy-duty high speed steel with a titanium nitride (TiN) coating, it runs cooler and resists wear longer than uncoated HSS bits. The 135-degree split point reduces walking on entry and requires no center punch on most surfaces. At 2.75 inches overall length with a 1.625-inch flute, it fits standard drill chucks and right-angle attachments. The parabolic flute geometry clears chips aggressively, making it well suited for deeper hole applications where chip packing is a concern.

This bit is intended for right-hand cutting in steel alloy stock, making it a practical choice for HVAC fabrication, electrical conduit work, plumbing rough-in, and general trade sheet metal or structural drilling. The straight cylindrical shank at 0.125 inches diameter seats in any 3-jaw chuck or quick-change system. Series 150DHT is CHICAGO-LATROBE's heavy-duty TiN-coated line, built for repetitive production use where bit life and hole quality matter. Sold individually, it fits tool kits and replacement stock equally well.

Key Features

• 135-degree split point reduces entry walking and eliminates the need for center punching on most materials
• Titanium nitride (TiN) coating increases surface hardness and extends cutting life versus bare HSS
• Parabolic flute design promotes fast, consistent chip evacuation in deeper holes
• Web-thinned, tapered web construction reduces thrust required during drilling
• Heavy-duty grade HSS rated for steel alloy as the primary workpiece material
• Straight cylindrical shank fits standard 3-jaw chucks and quick-change adapters without modification

Compatibility

Designed as an OEM-style replacement or direct addition for any application requiring a 1/8-inch jobber-length drill bit with a straight cylindrical shank in standard drill chucks and right-angle drivers.

Installation Notes

Install and remove drill bits only with the drill unplugged or the tool battery removed. Secure the shank fully into the chuck jaws and tighten with a chuck key before use. Wear ANSI-rated eye protection when drilling metal. Do not exceed the rated RPM for the bit diameter or workpiece material, and apply cutting fluid when drilling steel alloy to maximize bit life.
