Hertel 61698387 Screw Machine Drill Bit 1/16 in Hss

Product Description

The HERTEL 61698387 is a screw machine length (stub length) twist drill bit designed for high-rate drilling in metal, wood, and general-purpose materials. Built from high speed steel with an oxide finish, this bit measures 0.0625 inches (1/16 inch) in diameter with an overall length of 1.625 inches and a flute length of 0.625 inches. The 118-degree standard point angle provides reliable self-centering on flat and curved surfaces. The shorter-than-jobber body length delivers added rigidity and reduced deflection, making it well suited to production drilling and CNC drilling applications.

Screw machine length drill bits are standard in machine shops, production facilities, and trade service work wherever a compact, rigid drill profile is needed. This bit fits drill presses, CNC machining centers, and handheld power drills with standard straight-shank chucks. The 0.0625-inch diameter places it in the small-diameter range used frequently for pilot holes, tapping prep, sheet metal, and light structural work. Licensed machinists, HVAC fabricators, electricians, and plumbers all reach for stub-length bits when working in tight bores or high-cycle drilling setups.

Key Features

• High speed steel construction for durability across ferrous and non-ferrous materials
• Oxide finish provides mild lubricity and corrosion resistance during cutting
• 118-degree standard point angle for general-purpose drilling on flat and rounded stock
• Stub (screw machine) length body reduces deflection and improves hole accuracy
• Right-hand cut with 2-flute regular spiral for efficient chip evacuation
• Straight-cylindrical shank fits standard 3-jaw drill chucks without adapters
• ANSI specification designation confirms dimensional conformance

Compatibility

Designed as a general-purpose screw machine length drill bit conforming to ANSI specifications, compatible with any drill press, machining center, or handheld drill fitted with a standard straight-shank chuck capable of holding a 0.0625-inch diameter bit.

Installation Notes

Install and remove drill bits only when the drill or machine spindle is fully stopped and power is locked out or disconnected. Secure the straight-cylindrical shank firmly in the chuck and verify there is no runout before beginning a cut. This bit does not support coolant-through operation; apply cutting fluid externally when drilling hard metals to extend tool life. Follow applicable shop safety standards and machine-guarding requirements during all drilling operations.
