High Speed Steel NC Spotting Drill Bit 2241L 3/8″ x 3-1/2″ Shank

Description

Product Overview

The YG-1 2241L NC spotting drill bit is engineered for high‑precision applications in modern manufacturing environments. Constructed from high speed steel alloyed with 8% cobalt, the tool delivers superior hardness, heat resistance, and wear resistance, ensuring a long service life even under demanding conditions. Its 120° point angle creates a sharp, clean entry that minimizes material deformation, while the slow spiral geometry reduces chip buildup and provides smoother cutting action. The straight shank is designed for seamless compatibility with standard NC and CNC spindle holders, delivering consistent runout and stability during high‑speed operation. Measuring 3/8″ in diameter and 3‑1/2″ in length, this bit offers a balanced profile that supports both centering and chamfering in a single pass, improving workflow efficiency.

Usage

This spotting drill is ideally suited for precision centering and chamfering tasks on CNC‑controlled machinery, including milling machines, drilling centers, and multi‑axis routers. It excels in applications such as aerospace component fabrication, automotive part machining, and general metalworking where exact hole placement is critical. The tool’s robust construction allows it to handle a variety of materials, including stainless steel, alloy steel, and hardened metals, making it a versatile choice for production lines and prototype workshops alike. Operators benefit from the reduced need for secondary tooling, as the bit’s geometry enables simultaneous drilling and edge finishing, saving time and reducing tool changes.

FAQ

What material is the drill bit made from?

The bit is made from high speed steel alloyed with 8% cobalt, offering high hardness, heat resistance, and durability for demanding machining tasks.

Can this bit be used on stainless steel?

Yes, the alloy composition and heat‑treated construction allow it to effectively drill stainless steel and other hardened alloys without excessive wear.

What is the advantage of the 120° point angle?

A 120° point provides a sharper entry, reducing the force required to start the hole and minimizing deformation of the workpiece, which is essential for precise centering.

Is the straight shank compatible with all CNC machines?

The straight shank conforms to standard CNC spindle dimensions, making it compatible with most CNC drilling and milling machines that accept 3/8″ shank tools.

How does the slow spiral benefit the drilling process?

The slow spiral reduces chip evacuation resistance, allowing smoother cutting, lower heat buildup, and extended tool life, especially in tougher materials.
