Import 27435 Jobber Drill Bit 13mm Hss 118 Degree

Product Description

The IMPORT 27435 is a high speed steel (HSS) jobber-length drill bit designed for general-purpose drilling in steel, cast iron, and similar ferrous materials. The bit measures 13.00 mm (0.5118 inches) in diameter and features a standard 118-degree point angle suited for flat-surface entry on common metals. An oxide coating reduces friction and provides basic corrosion resistance during service. The straight cylindrical shank is compatible with standard drill chucks, and the regular spiral flute promotes efficient chip evacuation. Overall length is 152.00 mm (5.9844 inches) with a flute length of 114.00 mm (4.4844 inches). This bit is sold individually and is a stock trade-supply item for metalworking and mechanical service shops.

The 27435 is intended for right-hand drilling operations in ferrous workpieces including mild steel and cast iron. It suits production and maintenance drilling tasks where a general-purpose HSS bit is the specified tool. The web-thinned, tapered-web design reduces entry resistance and keeps point geometry consistent through resharpening cycles. Typical users include machinists, millwrights, pipefitters, and mechanical contractors drilling clearance, pilot, or through-holes in structural and mechanical components.

Key Features

• 13.00 mm (0.5118 inches) diameter — falls within the 12.50 to 15.00 mm general-purpose size range
• 118-degree standard point angle for entry on flat and slightly curved metal surfaces
• High speed steel construction for durability across ferrous materials including steel and cast iron
• Oxide coating reduces friction and provides light corrosion protection
• Web-thinned tapered web reduces thrust force at bit entry
• Right-hand regular spiral flute promotes continuous chip clearance
• Straight cylindrical shank fits standard 3-jaw drill chucks without adapters

Compatibility

Designed as a general-purpose jobber drill bit for use in standard drill chucks accepting a 0.5118-inch straight shank, suitable for bench drills, drill presses, and hand drills used on steel and cast iron workpieces.

Installation Notes

Secure the shank fully in the drill chuck and confirm chuck key is removed before operation. Use appropriate cutting fluid or coolant for ferrous materials to extend edge life, noting this bit does not support coolant-through delivery. Ensure workpiece is clamped or fixtured before drilling to prevent rotation. Inspect cutting edges before each use and resharpen or replace when point geometry shows wear.
