Helical Solutions 83754 Drill Mill 1/4 Inch 4 Flute Solid Carbide

Product Description

The HELICAL SOLUTIONS 83754 is a solid carbide drill mill designed for combination drilling, chamfering, and end milling operations in a single tool. Built with a 90-degree point angle and four right-hand flutes, it handles spot drilling, countersinking, and profiling without a tool change. The 1/4 inch mill diameter and matching 1/4 inch shank make it compatible with standard collet systems. A Tplus coating reduces friction and extends tool life in ferrous and non-ferrous materials. At 2.5 inches overall length with a 3/4 inch length of cut, it fits most standard milling setups and machining centers.

This drill mill is suited for job shops, production machining environments, and toolroom applications where multi-function capability reduces cycle time. It performs well in light to medium-duty milling, drilling, and chamfering on a wide range of workpiece materials. The combination chamfer and end mill geometry makes it a practical choice for machinists working on CNC machining centers or manual knee mills where tool changes are a bottleneck.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cutting conditions
• 90-degree point angle enables accurate spot drilling and chamfering in a single operation
• Four right-hand flutes provide efficient chip evacuation and a smooth finish
• Tplus coating reduces heat buildup and extends tool life compared to uncoated carbide
• 1/4 inch shank diameter fits standard ER collets and end mill holders
• 2.5 inch overall length with 3/4 inch length of cut suits shallow to mid-depth applications

Compatibility

Designed as an OEM-style replacement or direct tooling option for CNC machining centers and manual mills accepting 1/4 inch shank end mills and drill mills.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is in an e-stop or powered-down state before changing tooling. Secure the shank in a clean, properly sized collet or end mill holder and torque the retention nut to the holder manufacturer specification. Verify runout with a dial indicator before beginning a cut to protect both the tool and the workpiece.
