Cle-line C22883 Jobber Drill 8.50 Mm Hss Oxide

Product Description

The CLE-LINE C22883 is a jobber-length twist drill designed for general-purpose drilling in a wide range of materials. Built from high speed steel (HSS) with an oxide finish, it delivers solid wear resistance under continuous shop use. The drill features an 8.50 mm diameter, a 118-degree standard point angle, and a two-flute right-hand spiral configuration. Overall length is 117.00 mm (4.6063 inches) with a 75.00 mm (2.9528-inch) flute length. The straight-cylindrical shank seats securely in standard drill chucks. Web thinning reduces thrust load at the cutting edge, making starts cleaner and more consistent on production runs.

This drill is suited for drilling aluminum and a broad range of ferrous and non-ferrous materials in job shop, maintenance, and light manufacturing environments. The Series 1899 design follows ASME B94.11M and DIN 338 standards, making it a recognized jobber-length format compatible with conventional drill presses, hand drills, and CNC drilling operations where a straight-shank jobber bit is appropriate. No coolant-through capability is present, so external coolant or cutting fluid application is recommended when drilling harder or thicker stock.

Key Features

• 8.50 mm (0.3346 inch) diameter with diameter tolerance of +0.0000 to -0.0010 inches
• 118-degree standard point angle for general-purpose entry in metals and plastics
• High speed steel construction with oxide coating for added wear resistance
• Web-thinned tapered web reduces cutting thrust and improves chip clearance
• Right-hand, regular spiral, two-flute design for efficient chip evacuation
• Meets ASME B94.11M and DIN 338 standards - Series 1899

Compatibility

Designed as a general-purpose jobber drill suitable for aluminum, wood, plastics, and general ferrous materials; primary workpiece material classifications include K, N, and P per standard material groupings.

Installation Notes

Install into a keyed or keyless chuck rated for the shank diameter and confirm the bit is fully seated before operation. Power down the drill press or disconnect the tool from its power source before changing bits. For best results in aluminum or softer metals, apply a cutting fluid to reduce heat buildup and extend tool life. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
