Cleveland C49145 Taper Length Drill Bit 0.5625 in

Product Description

The CLEVELAND C49145 is a carbide-tipped taper length drill bit designed for drilling operations that require extended reach beyond what a jobber-length bit provides. With a 0.5625 inch (9/16 inch) diameter, a 118-degree standard point angle, and an overall length of 8.25 inches, this bit handles tough materials in production and maintenance drilling applications. The carbide-tipped construction resists wear at elevated cutting speeds, and the gold finish indicates a surface treatment applied during manufacturing. Web thinning reduces thrust requirements at the point, making entry cleaner and more efficient.

This drill bit suits metalworking applications in machine shops, maintenance facilities, and manufacturing environments where a standard jobber-length bit lacks the reach needed to complete the bore. The Series 2745 taper length format is a recognized industrial standard for drilling through structural components, fixtures, and deep-reach workpieces. A tanged shank provides a positive drive connection in compatible taper shank spindles and drill holders. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole drilling in steel, cast iron, and similar ferrous materials.

Key Features

• Carbide-tipped construction for extended tool life in abrasive and hard materials
• 118-degree standard point angle for general-purpose drilling in ferrous metals
• Web-thinned tapered web reduces point thrust and improves hole entry
• Tanged taper shank provides positive drive in compatible spindles
• 4.875 inch flute length and 8.25 inch OAL for extended-reach drilling
• Right-hand cut regular spiral flutes promote chip evacuation

Compatibility

Designed as an OEM-style taper shank drill bit compatible with taper shank drill chucks and spindles accepting a 0.5625 inch tanged shank. Verify taper designation and shank fit against your machine spindle before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully de-energized and locked out before seating or removing the shank. Clean the taper shank and spindle bore of chips, oil, and debris before insertion to ensure full seating and concentricity. Follow applicable shop safety procedures and machine manufacturer guidelines for taper shank tooling.
