Value Collection 01359199 Drill Bit Letter S Hss

Product Description

The VALUE COLLECTION 01359199 is a screw machine length drill bit sized to Letter S (0.3480 inches decimal equivalent), designed for general-purpose drilling in metal, wood, and plastic. Screw machine length bits are shorter than jobber-length bits, which improves rigidity and reduces deflection in tight spaces or on drill presses. The 118-degree standard point angle suits a wide range of materials, while the high-speed steel (HSS) construction with oxide coating provides basic lubricity and corrosion resistance. Two regular spiral flutes evacuate chips efficiently during through-hole and blind-hole drilling. This bit is installed and used by machinists, maintenance technicians, and trade professionals working in fabrication or field service environments.

This drill bit is suited for general-purpose production and maintenance drilling applications where a shorter, stiffer bit is preferred over standard jobber length. The straight cylindrical shank fits standard drill chucks on bench drill presses, hand drills, and drill motors. The 1.75-inch flute length accommodates moderate-depth holes without excessive bit flex. The web-thinned tip reduces the thrust force required at breakthrough, making it practical for hand-held drilling operations on light-gauge metal and similar materials.

Key Features

• Letter S size — 0.3480 inches decimal equivalent for precise hole sizing
• 118-degree standard point angle for general-purpose use across common materials
• High-speed steel (HSS) construction with oxide coating for basic wear and corrosion resistance
• Screw machine (stub) length at 3.0625 inches OAL improves rigidity and reduces deflection
• Web-thinned tip reduces drilling thrust and makes hand-held use more manageable
• Right-hand cutting, regular spiral flute design for standard clockwise-rotation drilling

Compatibility

Designed as a general-purpose replacement or stock drill bit for any standard drill chuck accepting a straight cylindrical shank in the 0.3480-inch size range.

Installation Notes

Install the straight shank fully into the drill chuck and tighten securely before operation. Ensure the workpiece is clamped or secured to prevent rotation during drilling. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and improve hole quality. Always wear eye protection and follow applicable shop safety practices when operating drilling equipment.
