Rotational speeds and feed for High-Speed Twist Drills
MATERIAL AND CUTTING SPEED (FT PER MINUTE)
Rotational speed value for carbide twist drills are 200 to 300 percent higher than H.S.S.
For Aluminum H.S.S.drill CUTTING SPEED (FT PER MINUTE) is 300.

The threshold for aluminum is something like 60,000 sfm.  Aluminum was drilled  at 24,000 sfm with an uncoated carbide insert, without any harm to the aluminum or the insert. Within a safe working environment, one need not be afraid to use higher cutting speeds as  higher speeds in aluminum get you both better tool life and a better surface finish.

In a production test that compared drilling speeds for brass alloys with those for two steel types, brass won hands down, with drilling speeds that reached 2,000 Surface Feet per Minute (SFM). By contrast, speeds for 304L stainless steel reached only 250 SFM, and for 12L14, only 800 SFM. The test consisted of drilling at least 1,000 1.50″-deep holes before reaching end of life on a 0.50” carbide drill. Brass also required significantly less power than both steels to remove comparable amounts of material.

Sandvik Coromant’s CoroDrill 860 -  distinctive geometry boosts speed when drilling steel components

OCT 24, 2012
The tool is made of a tough, new carbide grade, GC4234.

Its use gives 50% lower cutting force and hence results in  fewer problems when encountering issues such as weak fixtures, thin-walled components or undesirable loads on the cutting edge.
impressive results.

Benfits observed. In drilling 6.90-mm diameter through-holes for thread tapping in engine plates made from low alloy steel (using MQL), CoroDrill 860 offered 62% gains in both productivity and tool life against a competitor product. Penetration rates have increased from 387 to 627 mm/min.

In producing a chamfered 8.5-mm diameter through-hole in a wheel hub made from an unalloyed steel casting of 255HB hardness (using flood oil coolant), CoroDrill 860 is offered 98% greater productivity.

In another example, it provided  productivity gains of 100% when drilling 10.50-mm through-holes in low-alloy steel (stacked) drive axles.

The standard diameter range of CoroDrill 860 is 3-20 mm (0.118−0.787 inch) in lengths of 3-8 x D. The achievable hole tolerance is IT8–IT9.  As through-coolant is available on all drills. Through-the-spindle coolant, coupled with drills offering internal ducts for delivering coolant directly to the tip of the tool the tool can have extended drill life at almost any speed used in practice now.
