Sumitomo U101334 Carbide Replaceable Tip Drill Smd 35/64 in

Product Description

The SUMITOMO U101334 is a solid carbide replaceable tip drill designed for high-productivity metal cutting in demanding machining environments. Built to the SMD series specification, this drill features a 35/64-inch diameter, a 140-degree included point angle, and an MTL-C insert geometry. The cutting tip carries a dual-layer TiAlCr and TiSi coating applied via PVD process, which delivers elevated hardness and heat resistance at the tool-workpiece interface. Through-coolant capability allows cutting fluid to be delivered directly to the cutting zone, supporting chip evacuation and thermal control at depth. This tool is intended for use by machinists and tool-and-die technicians operating CNC machining centers.

The U101334 is suited for drilling cast iron and steel workpieces, designated by material codes K and P respectively. The replaceable tip design reduces tooling cost by allowing tip exchange without discarding the drill body. Typical applications include production drilling in automotive, mold-and-die, and general metalworking shops where consistent hole quality and extended tool life are required across moderate-to-high spindle speeds.

Key Features

• 35/64-inch drill diameter with 140-degree point angle for aggressive chip splitting
• Solid carbide tip in MTL-C insert geometry for rigid, precise cutting
• TiAlCr and TiSi dual-layer PVD coating for thermal and wear resistance
• Through-coolant design directs fluid to the cutting edge for chip evacuation and heat management
• ACX70 manufacturer grade optimized for cast iron and steel
• Replaceable tip construction extends drill body service life

Compatibility

Designed for use with SMD series drill bodies accepting MTL-C replaceable carbide tips. Primary workpiece materials are cast iron (ISO material code K) and steel (ISO material code P).

Installation Notes

Installation of replaceable carbide tips should be performed by a qualified machinist following the tool manufacturer's torque and seating procedure for SMD series bodies. Ensure the drill body is clean and free of chips or debris before seating the tip. Confirm through-coolant supply pressure and flow rate are within machine specifications before running. Inspect the tip and body interface for secure seating before each use.
