I am on a budget, but if I’m going to get something, I want something that will last a while I probably can’t get brushless right now.
Until now the latest edition to the Hercules line at Harbor Freight was the 15 amp dual bevel compound sliding miter saw. That just changed with a new 11 amp 4 ½” angle grinder model HE61P. My thoughts: as always it’s nice to see new products with excellent specs coming out at Harbor Freight. This Hercules® 11 Amp Heavy Duty Angle Grinder has a high power all ball bearing motor built for professional jobsite use.
I have the Chinese flap disks because I did the only pay shipping offer with Benchmark but I buy higher end cut off wheels to use with my $10 grinder. Most guys I know don’t use the guard, glasses, or ear pro no matter what grinder they own and that same accident can happen with any brand when you throw caution to the wind. I use all that plus a face shield and leather mechanics gloves with rubber armor on the top.
“The specs in the Chicago Angle Grinder manual show that it is a 4-1/2″ grinder with a reported speed of 11,000 RPM. The spindle is the virtually standard 5/8″ by 11 TPI and it uses an arbor hole of 7/8” also very common with this type of grinder. “Another point of concern is the lack of brute power during grinding. I know that you should not lean on any tool with a grinding disk but the Chicago Angle Grinder loses RPM well before I could apply anything near what I consider to be excess force. Quantifying the amount of force being applied is very difficult outside of a laboratory so I compared the grinding capabilities of the Chicago Angle Grinder against my DeWalt DW818 and Bosch #1380 Slimline 4-1/2″angle grinders, using the same disk that came with the Chicago Angle Grinder. My best advice is to pass on the Chicago Angle Grinder and save up for a better angle grinder.
The new Harbor Freight Hercules brushless angle grinder features an 8500 RPM motor, quick-adjust guard, electronic soft-start, cleanable air vents, and spindle lock. Harbor Freight is only selling the Hercules 20V angle grinder as a bare tool, which means you’ll need a separate battery and charger. This is an expansion of Harbor Freight’s Hercules 20V cordless power tool line, and although it’s their second brushless angle grinder, it’s just the start of their Hercules brushless tool selection.
Normally an expensive item, but Harbor Freight sells one-ton hoists for $60. See more tips for when working by yourself. Many of the various saw blades you’ll find at Harbor Freight aren’t great choices for precision work. If you’re a DIYer considering buying a floor jack and stands for home car maintenance, do not whip out that credit card until you’ve seen what Harbor Freight has to offer.
