Accupro 4500165 Jobber Drill 15/32 in Solid Carbide Tialn

Product Description

The ACCUPRO 4500165 is a solid carbide jobber-length drill bit designed for high-performance drilling in hard and abrasive materials. It carries a TiAlN (titanium aluminum nitride) coating that raises surface hardness and heat resistance, extending tool life in demanding cutting conditions. The bit measures 15/32 inch (0.4688 inch) in diameter with an overall length of 6-7/32 inches and a 140-degree point angle suited for fast, centered starts. Coolant-through capability allows internal delivery of cutting fluid directly to the tip, reducing heat buildup during deep or high-speed operations. A licensed HVAC tech, machinist, or tool-and-die professional will find this bit appropriate for precision work in ferrous and non-ferrous metals.

This drill bit is built for production and job-shop environments where tool life and hole quality matter. It fits standard drill chucks and CNC spindles that accept a straight cylindrical shank in the 15/32 inch diameter. The right-hand spiral flute configuration and R-thinned web design support efficient chip evacuation and reduced thrust force. Typical applications include through-hole and blind-hole drilling in steel, stainless, cast iron, and high-temperature alloys where a standard high-speed steel bit would wear prematurely.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• TiAlN coating increases surface hardness and thermal resistance at the cutting edge
• 140-degree point angle for fast engagement and reduced walking on entry
• Coolant-through design delivers fluid directly to the cutting tip
• R-thinned web reduces thrust and improves chip flow
• Regular spiral flute at a 5xD flute-to-diameter ratio for balanced strength and chip clearance

Compatibility

Designed as an OEM-style replacement or direct-fit upgrade for any application requiring a 15/32 inch straight-shank jobber drill bit in solid carbide with a TiAlN coating.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with carbide tooling handling. Carbide is brittle - avoid dropping or striking the bit against hard surfaces before or after use. Secure the straight shank fully within the chuck or collet to the recommended grip depth before beginning any cut. Verify spindle speed and feed rate settings against the material being drilled; running carbide tooling at incorrect parameters can cause premature chipping or breakage.
