Hertel 83246504 Straight-flute Drill Bit No. 17 Solid Carbide

Product Description

The HERTEL 83246504 is a straight-flute drill bit sized to No. 17 wire gauge, measuring 0.1730 inches in diameter. Built from C2-grade solid carbide with a bright, uncoated finish, it features a 140-degree notched point and a web-thinned design that reduces thrust and improves chip flow at entry. With two right-hand cutting flutes and a diameter tolerance of +0.0000 to -0.0005 inches, this bit is engineered for consistent, close-tolerance holes in demanding workpiece materials. It is suited for machinists, toolroom technicians, and maintenance professionals who require reliable performance in hard or abrasive stock.

This drill bit is designed for use on chrome alloy, heat-treated alloy, nickel alloy, stainless steel, steel, and titanium alloy materials. It fits typical application scenarios in precision machining, aerospace component work, industrial maintenance, and fabrication where tight hole tolerances and clean entry geometry are required. The 0.1730-inch shank diameter matches the cutting diameter, allowing direct chuck mounting in standard drill chucks, CNC machining centers, or drill presses without adapter sleeves.

Key Features

• Solid C2-grade carbide construction for hardness and wear resistance in alloy and stainless steel materials
• 140-degree notched point reduces walking and improves centering at drill entry
• Web-thinned geometry lowers axial thrust and eases chip evacuation
• Bright, uncoated finish maintains dimensional accuracy without coating buildup in tight-tolerance holes
• Diameter tolerance of +0.0000 to -0.0005 inches for close-fit hole applications
• Right-hand, two-flute straight configuration for use in standard rotating spindles

Compatibility

Designed as an OEM-style replacement or direct-use straight-flute carbide drill bit for CNC machining centers, drill presses, and manual mills accepting a 0.1730-inch shank diameter. Compatible with workpieces in chrome alloy, heat-treated alloy, nickel alloy, stainless steel, steel, and titanium alloy as stated by the manufacturer.

Installation Notes

This bit is installed by machinists or toolroom technicians in standard three-jaw chucks or collet holders rated for the 0.1730-inch shank. Ensure the spindle is fully stopped and locked out before changing tooling. Verify chuck or collet runout is within tolerance before use, as excessive runout accelerates carbide wear and can cause premature breakage. Carbide bits are brittle and should not be used in handheld drills or applications with significant lateral loading.
