Iscar 5531112 Jobber Drill Bit 2.5 Mm Solid Carbide

Product Description

The ISCAR 5531112 is a jobber length drill bit designed for precision holemaking in demanding industrial and machining applications. Built from submicron solid carbide and coated with TiAlN, this drill bit delivers extended tool life and thermal resistance when cutting hard and abrasive materials. It measures 2.5 mm in diameter with an overall length of 60 mm, a flute length of 20 mm, and a shank diameter of 3 mm. The 140-degree drill point angle promotes self-centering and reduces thrust force at entry. A spiral flute with regular helix ensures efficient chip evacuation. This tool is installed and operated by machinists, tool and die specialists, and CNC machine operators working in production and job shop environments.

The 5531112 is suited for holemaking in cast iron, steel, stainless steel, hard materials, non-ferrous metals, superalloys, and titanium. It belongs to ISCAR Series SCD-AP6 and conforms to DIN 6537 specification. The straight-cylindrical shank is compatible with standard drill chucks and collet systems. With a 6xD flute-to-diameter ratio and a maximum drilling depth of 15 mm, this bit is optimized for short, precise holes in high-strength workpieces. It cuts in a right-hand direction and is not configured for coolant-through delivery.

Key Features

• Submicron solid carbide construction for hardness and wear resistance in demanding materials
• TiAlN coating provides thermal barrier and extended tool life at elevated cutting temperatures
• 140-degree point angle reduces walking and entry thrust across a range of workpiece materials
• Regular spiral flute geometry promotes consistent chip evacuation in short-hole applications
• Straight-cylindrical shank fits standard chucks and collet holders without adapters
• Conforms to DIN 6537 and ISO 13399 standards for dimensional consistency

Compatibility

Designed as a direct-fit replacement or standard selection within the ISCAR SCD-AP6 series for holemaking in cast iron, steel, stainless steel, hard materials, non-ferrous metals, superalloys, and titanium workpieces requiring a 2.5 mm hole diameter.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Secure the straight-cylindrical shank fully in the chuck or collet and verify runout before commencing cuts. Power down and lock out the machine before changing or inspecting the bit. Do not exceed the specified maximum drilling depth of 15 mm per pass without confirming chip clearance.
