STAR CUTTER CO.’s solid-carbide drill designed for machining aluminum castings has proven to achieve 1.5X to 4X the tool life of competitive offerings in automotive prismatic applications, such as valve bodies, housing, and transmission cases, to name a few. Based on specially selected material grades and point geometries, the drills are optimized for each specific application.
Available in diameter sizes starting at 4 mm, these drills are manufactured from a selection of more wear‐resistant carbide grades than typically used in these applications, resulting in longer tool life. Additionally, special bolt‐hole circles and coolant hole sizes assist in eliminating OD aluminum build up and aid in flushing chips away from the workpiece.
The drills are available with various advanced coatings, and/or highly polished carbide to eliminate build up and reduce overall tool wear.
The standard point geometry has been established based on the part entry conditions and is modified as needed based on the condition of the casting. The developer requests a casting print and tooling layout for each drill order. Learn more at www.starcutter.com
