What this tool does
The Cleveland C40505 is a 2-flute HSS single-end drill mill designed for milling operations. It suits machinists and fabricators who need a combined drilling and milling cutter in one tool. The uncoated high-speed steel body handles general-purpose metal cutting. It is not for buyers who require coated tooling for high-temperature alloys.
Thermals noise and power
Heat generation depends on the machine spindle speed, feed rate and workpiece material rather than the cutter itself. The uncoated HSS construction tolerates typical milling temperatures when proper coolant or lubrication is applied. No power-draw or noise figures are inherent to the accessory.
90-degree point angle
The 90-degree point angle determines the chamfer profile and starting behaviour in the workpiece. This fixed geometry suits centred drilling and chamfering tasks that call for a right-angle included angle. Select a different point angle if the joint design or hole preparation requires a sharper or shallower profile.

Questions about this item
How do I install the Cleveland C40505 drill mill and what step do people often get wrong?
Secure the 1 in shank fully in the collet or chuck before tightening; the common error is leaving a gap that lets the tool pull out under load.
What maintenance or replacement will the Cleveland C40505 need later?
The uncoated high-speed steel flutes will dull with use; plan to resharpen or replace the tool once the 90-degree point no longer cuts cleanly.
What limit appears first on the Cleveland C40505 during sustained cutting?
Heat buildup in the uncoated HSS body reduces edge hardness fastest, so cutting speed must drop before the 90-degree point wears excessively.
