Value Collection 01195593 Screw Machine Drill Bit 1mm

Product Description

The VALUE COLLECTION 01195593 is a screw machine length cobalt drill bit designed for short-reach, high-precision drilling in metal and hard materials. Built from heavy-duty cobalt steel with a straw finish, it measures 1.00 mm in diameter (0.0394 inches) and carries a 135-degree split point that self-centers on contact and reduces walking without a center punch. The overall length is 26.00 mm (1.0236 inches), and the flute length is 6.00 mm. With a 2-flute regular spiral configuration and a straight shank, this bit is suited for use in drill presses, CNC machines, and handheld power tools where compact reach and accuracy matter.

Screw machine length bits are used when standard jobber-length bits offer too much flex or overhang. This 1.00 mm bit is commonly used in metal fabrication shops, machine shops, and production environments for drilling small-diameter holes in ferrous and non-ferrous metals. The cobalt construction provides heat resistance during high-speed or dry drilling, making it a durable choice for repetitive operations on hard stock. Right-hand cutting direction is standard for conventional drill operation.

Key Features

• 1.00 mm diameter cobalt construction for heat resistance in hard-material drilling
• 135-degree split point for self-centering entry without a center punch
• Screw machine length body at 26.00 mm overall for reduced deflection in tight setups
• 2-flute regular spiral geometry for efficient chip evacuation
• Straight shank compatible with standard chucks and collets
• Straw finish indicates cobalt-grade heat treatment without added coating buildup

Compatibility

Designed as an OEM-style replacement or standard stock drill bit for use in screw machine length applications across general metalworking and machining operations.

Installation Notes

This bit is installed by machinists and metalworkers in drill press, mill, or CNC spindle setups. Secure the straight shank firmly in the chuck or collet before operation and confirm runout is within acceptable tolerance for the diameter. At 1.00 mm, feed rate and spindle speed must be matched carefully to material hardness to avoid bit breakage. Coolant-through is not supported on this bit, so adequate surface-applied coolant or dry-cutting practices should be used per shop procedure.
