Hertel 61698999 Screw Machine Drill Bit 15/32 Inch Hss

Product Description

The HERTEL 61698999 is a screw machine length drill bit designed for high-speed steel cutting applications in metalworking and light industrial environments. It measures 15/32 inches (0.4688 inches decimal) in diameter with a 3-5/8 inch overall length and a 2-1/8 inch flute length. The 118-degree standard point angle provides a versatile entry geometry suited for general-purpose drilling in a wide range of materials. The oxide coating helps reduce friction and surface wear during cutting. This bit is installed and used by machinists, tool and die workers, maintenance mechanics, and industrial trades professionals working with drill presses, CNC machines, lathes, or hand-held power drills.

Screw machine length drill bits are shorter than jobber-length bits, which increases rigidity and reduces deflection in production drilling setups. This makes the 61698999 well suited for close-tolerance work on drill presses and milling machines where a shorter tool path improves accuracy. The right-hand spiral flute design evacuates chips effectively during through-hole and blind-hole drilling. The straight cylindrical shank is compatible with standard drill chucks and collets. General-purpose grade designation makes this appropriate for a broad range of ferrous and non-ferrous materials.

Key Features

• 15/32 inch diameter with 0.4688 inch decimal equivalent for precise sizing
• 118-degree standard point angle for general-purpose entry geometry
• High-speed steel construction provides heat and wear resistance during cutting
• Oxide coating reduces friction and surface galling
• Screw machine length body increases rigidity and reduces bit deflection
• Right-hand cut with 2-flute spiral design for efficient chip evacuation
• Straight cylindrical shank fits standard drill chucks and collets

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard drill chucks and collets sized to accept a straight cylindrical shank in the 0.4500 to 0.5000 inch diameter range, per ANSI specification designation.

Installation Notes

This drill bit is installed and operated by machinists and maintenance trades using drill presses, milling machines, lathes, or power hand drills. Ensure the spindle is fully stopped and the drill chuck is tightened securely before operation. Confirm chuck capacity is rated to accept a 15/32 inch straight shank before use. Follow applicable shop safety procedures and machine guarding requirements when operating rotating tooling.
