Cleveland C14809 Screw Machine Drill Bit 6.6mm Cobalt

Product Description

The CLEVELAND C14809 is a cobalt screw machine length drill bit designed for heavy-duty drilling in demanding shop and field applications. It measures 6.6 mm (0.2598 inches) in diameter with a 70 mm (2.756 inches) overall length and features a 135-degree split point that reduces walking and requires no center punch on most surfaces. The two-flute, right-hand spiral design clears chips efficiently in shorter-reach setups. M42 cobalt construction gives the bit elevated heat and wear resistance compared to standard HSS bits, making it appropriate for alloy steels, aluminum, and other abrasive workpiece materials. Licensed machinists, pipefitters, and fabricators are the primary users.

The C14809 is built to ASME B94.11M and conforms to DIN 1897 and ANSI specifications, making it a recognized standard screw machine length format. The screw machine length profile — shorter than jobber length — suits drill presses, turret lathes, CNC machining centers, and hand-held drilling operations where reduced stick-out improves rigidity and positional accuracy. Primary workpiece materials include alloy steels and aluminum. The straight-cylindrical shank (0.2598 inches diameter) seats directly in standard drill chucks without an adapter.

Key Features

• M42 cobalt construction for elevated heat and wear resistance in hard or abrasive materials
• 135-degree split point reduces thrust and minimizes bit walking on entry
• Web-thinned, parallel web geometry for improved chip evacuation and reduced cutting torque
• Screw machine (stub) length provides added rigidity over jobber-length bits in tight setups
• Right-hand cut with regular spiral and 31 mm (1.220 inches) flute length
• Conforms to ASME B94.11M, DIN 1897, and ANSI specification standards

Compatibility

Designed as a standard screw machine length drill bit for use in drill presses, CNC machining centers, turret lathes, and hand-held drills equipped with standard drill chucks accepting a 0.2598-inch straight-cylindrical shank. Suitable for alloy steel and aluminum workpieces as noted in manufacturer specifications.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with rotating cutting tools. Ensure the drill chuck is fully tightened and the workpiece is securely clamped or fixtured before beginning any operation. Always wear appropriate eye protection and follow applicable shop safety standards. Do not exceed the recommended speed and feed range for the workpiece material and bit diameter.
