![]() ![]() Verdict: Harbor Freight Hercules Drill Torque Skil finishes with a 74% average and Hercules sits at 77%. Skil is able to close the gap with the self-feed bit but doesn’t pick up enough to overtake Hercules. Hercules maintained 74% of its no-load speed with the auger bit while Skil was a little behind at 68%. The first round goes to the Harbor Freight drill. Higher efficiencies also tell us the drill can handle larger bits than the ones we’re testing easier. In “ The Truth About Drill Torque and Speed,” we explore this idea further.įor now, the takeaway is that the better the efficiency percentage, the lighter the load on the motor and the longer it’s likely to last. Every manufacturer has to choose the gearing to go with their motor, so a straight-up speed test doesn’t tell the whole story. Verdict: Harbor Freight Hercules Drill Drilling EfficiencyĮfficiency helps us balance the speed results by comparing how fast a drill works against the no-load speeds measured. With no-load on either drill, Hercules is 120 RPM faster in high and 91 RPM faster in low, so we expect it to be faster with a bit in it as well. DeWalt again won this battle, holding onto 550 RPM. Skil closed the gap, but still remained behind at 358 RPM. While neither one of these really struggled to finish the test, both are long way out from from the DeWalt DCD797’s 1948 RPM average that leads this class.ĭropping to low speed for the additional torque, Hercules put up a 423 RPM average with the self-feed bit. ![]() Skil’s average was nearly 200 RPM lower at 1212 RPM. With the auger bit in high speed, Hercules kept its speed up to 1409 RPM on average. To test their respective speeds, we measured them drill in OSB subfloor layers with a 3/4″ Bosch Daredevil High-Speed Auger bit and a 1-1/2″ Milwaukee SwitchBlade Self-Feed bit. Verdict: Skil 20V Compact Drill Speed Under Loadīoth of these drills are in our compact class. This one is in favor of Skil by a wide margin. Skil jumps in with a 5-year warranty that exceeds what even some of the Pro brands offer. ![]() Considering our chuck failure, we’d recommend that you do. You can buy a 1 or 2-year extended warranty if you like. Harbor Freight warranties their Hercules 20V drill for 90 days. Verdict: Harbor Freight Hercules Drill Warranty ![]()
