Sumitomo U101347 Replaceable Drill Tip ACX70 0.6563 in

Product Description

The SUMITOMO U101347 is a replaceable drill tip designed for indexable drilling systems in demanding metal-cutting operations. Built from solid carbide and coated with TiAlCr and TiSi via a PVD process, this tip delivers high wear resistance and thermal stability at the cutting edge. The 0.6563-inch cutting diameter and MTL-C insert geometry are engineered for precision hole-making in cast iron and steel workpieces. The tip also features coolant-through capability, allowing pressurized coolant to reach the cutting zone directly and extend tool life. It belongs to the SMD series of replaceable-tip drilling systems and carries the ACX70 grade designation. Machining professionals in production and job-shop environments rely on this style of tip for consistent, repeatable performance without full tool replacement.

This drill tip is intended for use with compatible SMD-series drill bodies in metalworking applications targeting cast iron and steel materials. It is suited for CNC machining centers and drilling operations where coolant-through toolholding is available. The ACX70 grade and PVD coating combination makes it particularly effective in moderate- to high-speed cutting conditions where surface integrity and hole quality are critical. A 140-degree included angle supports self-centering entry and reduces thrust force in these materials.

Key Features

• Solid carbide construction with ACX70 grade for high hardness and wear resistance
• TiAlCr and TiSi PVD dual coating for thermal protection and reduced tool wear
• Coolant-through design delivers cutting fluid directly to the tip for improved chip evacuation and heat control
• MTL-C insert geometry optimized for cast iron and steel cutting
• 140-degree included angle for accurate entry and reduced axial thrust
• Replaceable tip format reduces tooling cost compared to full indexable-drill replacement

Compatibility

Designed for use with SMD-series replaceable-tip drill bodies that accept the MTL-C geometry in the 0.6563-inch diameter range. Intended for machining cast iron and steel workpieces on coolant-through capable spindles.

Installation Notes

Installation of this replaceable drill tip should be performed by a qualified machining professional following the toolholder manufacturer's torque and seating procedures. Ensure the drill body is clean and free of chips or debris before seating the tip. Verify the coolant-through circuit in the spindle and toolholder is functional and at the appropriate pressure before beginning the cut. Never exceed the recommended speed and feed parameters for the workpiece material and tip grade.
