Iscar 3411616 Solid Carbide Jobber Drill Bit 140 Degree

Product Description

The ISCAR 3411616 is a solid carbide jobber length drill bit engineered for high-performance holemaking in demanding materials. Built to the SCD series specification, it features a 140-degree point angle with a web-thinned, tapered web configuration that reduces entry thrust and improves centering. The AlTiCrSiN multi-layer coating provides heat and wear resistance during aggressive drilling cycles. A regular spiral flute geometry and right-hand cut combine with a straight shank for straightforward setup in standard drill chucks and toolholders. Coolant-through capability supports chip evacuation and tool life in deep-hole applications.

This drill bit is intended for holemaking and drilling operations in steel, stainless steel, cast iron, and hardened materials, covering ISO material groups P, M, K, and H. The 5xD flute-to-diameter ratio makes it well suited for moderate-depth holes in production machining environments, including CNC machining centers and manual machine tools where solid carbide tooling is specified for hard or abrasive workpieces.

Key Features

• 140-degree point angle with web-thinned, tapered web for reduced thrust and improved entry accuracy
• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiCrSiN multi-layer coating enhances heat resistance and extends tool life
• Coolant-through design supports chip evacuation in deep-hole drilling
• Regular spiral flute with right-hand cut for standard CNC and manual machine setups
• Straight shank compatible with standard drill chucks and toolholders

Compatibility

Designed as an OEM-style tooling solution for holemaking operations in steel, stainless steel, cast iron, and hardened materials (ISO P, M, K, H material groups) as part of the ISCAR SCD series.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician. Ensure the machine spindle and toolholder are fully powered down and at rest before loading or removing the bit. Secure the straight shank firmly in a compatible drill chuck or collet to the toolholder manufacturer's specified clamping torque. When coolant-through capability is used, verify that the machine coolant supply is properly connected and that coolant pressure is within the range recommended by the machine tool manufacturer.
