AD carbide drill enhances tool life and productivity at Schaeffler

Schaeffler Group USA Inc., the North American operation of the Schaeffler Group based in Herzogenaurach, Germany, is a leading global supplier of automotive and industrial components. Known for high‑precision systems used in engines, transmissions, chassis and bearing applications, the company provides bearing solutions, linear guidance systems, and repair and monitoring services. With about 110,000 employees and more than 250 locations in 55 countries, Schaeffler is among the world’s largest family-owned manufacturers.

Established in 1964, Schaeffler Group USA operates its regional headquarters for the Americas from a 60‑acre campus in Fort Mill, South Carolina, which includes administrative offices, two manufacturing plants and a Technology Center.

The company’s Cheraw, South Carolina, facility—employing 700 people across a modern 125,000‑square‑meter plant—recently sought a solid carbide drilling solution capable of handling multiple materials in both scheduled and unscheduled production. The site manufactures automotive components such as frax punches, cam pins and injection‑mold sliders, primarily in A2 and 1018 steel. Known for maximizing tool life, Schaeffler required a drill available in a wide range of standard sizes to stock its toolroom.

OSG USA was asked to recommend and test a non‑coolant carbide drill available in multiple stocked diameters and suitable for various materials. After reviewing requirements, OSG selected its AD carbide drill series, a next‑generation high‑performance line offered in 2xD and 4xD lengths from 2 to 20 mm. The AD series features a wavy point form for controlled chip breaking, wide flutes for smooth evacuation and stable machining torque, and OSG’s EgiAs coating for extended tool life.

A 4 mm AD‑4D DIN carbide drill (EDP# 8672400) was tested against two coated competitor drills on A2 steel (30 HRC). Each workpiece required three 0.1575‑inch blind holes drilled to 1.3 inches on a MAZAK VARIAXIS 500‑5X machining center using water‑soluble flood coolant. The component selected for the trial has been produced for seven years, with an annual volume of about 200 pieces.

Using identical cutting parameters, OSG’s AD drill delivered strong results: 80% longer tool life than the first competitor and 30% longer life than the second. For this 4 mm drill application alone, Schaeffler estimates annual savings of roughly $11,422 across various workpieces.

As a stocked, versatile and high‑performing solution, OSG’s AD drill series has proven to be a reliable partner in supporting Schaeffler Group USA’s commitment to efficient, intelligent and sustainable motion technology.
