What this tool is
The Cleveland C40523 is a two-flute high-speed steel drill mill with a 90-degree point angle. It is designed for machinists and fabricators who need a single cutter that can start holes and perform light milling in one pass.
Practical limits of a 90-degree drill mill
The fixed 90-degree point determines the maximum included angle for chamfering and spotting operations. High-speed steel construction means the tool wears faster than carbide when used in abrasive alloys or at elevated cutting speeds.
Check your setup before ordering
Verify that your machine spindle accepts the shank diameter supplied with this cutter. Confirm that your tool holder provides enough gauge length for the required depth of cut. Ensure your workpiece material and cutting parameters are compatible with high-speed steel tooling.

Questions about this item
Should I pick the 90-degree point or another angle for my milling tasks?
The C40523 comes with a fixed 90-degree point designed for combined drilling and chamfering; choose it when you need that specific included angle in a single pass.
What does the 90-degree point deliver once the tool is in the spindle?
It produces a centred hole and a matching 90-degree chamfer in one operation, reducing tool changes on CNC or manual mills.
How does the TiCN coating affect the cutting interface in practice?
The TiCN layer raises surface hardness and heat resistance, letting the high-speed steel flutes run faster in steel and cast iron without premature wear.
