BLUEROCK BRM-35A Guide: Black, Red and Bundle Differences
The red BLUEROCK BRM-35A and black BRM-35A-B belong together in a buying comparison: BLUEROCK says housing color is the machine difference, and its current manual covers the pair together. Bundle suffixes and seller titles still matter because a bare drill, a one-inch cutter set and a two-inch cutter set are different purchases.

BLACK BLUEROCK Tools Model BRM-35A Typhoon Magnetic Drill Roto-Broach
This listing belongs to the model family discussed here, but capacities and included items can vary by listing.
Check this Amazon offerWhat the current manufacturer pages agree on
The current BRM-35A/A-B manual specifies 120V, 50–60Hz, 10A, a 1200W motor, 595 RPM, a direct 3/4-inch Weldon arbor and a 2-inch maximum cutting depth. It lists the coolant bottle, feed handles, chuck, adapter, key, safety chain, protective plastic case and two hex wrenches.
The product pages state that housing color is the only difference between BRM-35A and BRM-35A-B. That supports a red-versus-black comparison, but it does not turn the separate BRM-60A-B, TYP-28A or TYP-75 into variants of the BRM-35A.
Resolve the capacity and revision details
The current manual and red product page both pair a 1-1/2-inch annular maximum with 35 mm, but those measurements are not equivalent: 1-1/2 inches is 38.1 mm. Treat 35 mm as the conservative documented ceiling unless BLUEROCK confirms otherwise for the exact machine and cutter.
The manual lists 6.5 inches of stroke while the current product pages list 7.5 inches. Do not average the figures or select the larger one. Use the exact revision's nameplate/manual and obtain manufacturer confirmation when the setup depends on the disputed extra inch.

Check AmazonA chuck adapter does not guarantee useful clearance
BLUEROCK notes that only short conventional drill bits fit with the supplied chuck attached and describes 3.5 inches between the base and bottom of that chuck. Before ordering for twist drilling, compare the complete chuck-and-bit arrangement with the working height available.
This is a different question from annular cutter capacity. If the job mostly involves small holes, consider whether a conventional drill press or another drill arrangement would make the sequence simpler. Buy the attachment you need for the work rather than assuming the included adapter makes every bit practical.
Compare bundles and keep BRM-60 separate
Price the basic drill, the useful cutters and any chuck upgrade separately. In the retained catalog, B00NPHBJ8C and B000GCNUEU are drill-only BRM-35A offers; B00PBAZUP4 is labeled with a one-inch cutter set; B00PBBAM56 and B00PBBP1E8 are labeled with two-inch cutter sets. A two-inch bundle label describes cutter depth, not a two-inch hole-diameter rating.
The BRM-60A-B, TYP-28A and TYP-75 listings are different machines with separate documentation. They are not alternative colors, upgrades or exact BRM-35A offers. A shopper comparing one of them needs a fresh check of capacity, spindle, speed, voltage and package instead of inherited BRM-35A limits.
Housing color is not evidence of better reliability, precision or cutting speed. Keep those claims out of the comparison unless matched test evidence for the exact revisions becomes available.
Questions, answered
Is the black BRM-35A-B more powerful than the red BRM-35A?
BLUEROCK states that color is the difference between these two named versions. Exact package and revision details still require confirmation.
Is the listed 35 mm capacity equal to 1-1/2 inches?
No. The manufacturer page contains an inconsistent conversion; confirm the permitted maximum for the exact machine if your hole is near the limit.
