Bosch GET65-5N: problems, parts and running costs

Checked: 2026-10-19

Summary

Owner complaints about the GET65-5N are behavioral, not mechanical: the turbo mode is too aggressive for general work, and retailer listings routinely swap this 5 in. model’s specs with the 6 in. GET75-6N sibling. No recurring bearing, switch or motor failure is documented for the exact model. Yearly running cost is just 5 in. abrasive discs and the occasional backing pad, but the research publishes no prices or replacement intervals, so no dollar figure can be given; the sander is a good buy near the bottom of the observed $269-365 store range and hard to justify at the top.

Common problems and fixes

Turbo mode is too aggressive for general sanding — the most common owner caution; turbo feels too aggressive, and the manual itself reserves Mode 1 for very rough surfaces and buffing, with Mode 2 (random orbit) for less durable surfaces and fine polishing. Fix: finish in Mode 2; the 3x stock-removal claim is a manufacturer figure, not an independent measurement. Usage issue, not a defect, so the 1-year limited warranty does not cover it. [4][8]
Listings swap the 5 in. model’s specs with the 6 in. GET75-6N — some pages quote the sibling’s 7.5 A, 6 in. and 0.18 in (4.5 mm) orbit numbers for this tool, whose own orbit is 0.09 in (2.25 mm), and a few listings inflate turbo removal to “up to 5 times”. Fix: verify part number 3601B57010 against Bosch’s own page before buying. [1][8][13]
Inconsistent finish quality — usually traced to grit sequence, worn discs or a dirty pad. Fix: fresh discs, clean pad, proper grit progression. Not a defect; wear items are excluded from the 1-year limited warranty. [4][16]
Bulky once a dust hose is attached — an owner refinishing stairs called the sander bulky with the dust setup next to a Festool RO 125 FEQ. Fix: plan the hose routing or attach dust extraction only for messy work. Not a defect. [5]
Dust collection seems weak — attributed to adapter fit and vacuum airflow rather than the sander itself; an owner using a plain shop vacuum still found pickup noticeably better than their previous sander. Fix: check adapter fit and vacuum airflow first. Not a defect. [4][6]
Certification labeling differs between the manual and one retailer table — the manual shows CSA and Intertek marks while the retailer’s spec table says ETL listed “No”. Fix: treat the retailer table as listing noise. [3][8]

Parts and consumables

Yearly running cost

Not enough data. The consumables are 5 in. The tool ships without a case, and the 1-year limited warranty excludes normal wear items, so discs and pads are routine owner costs rather than warranty items. [1][8][16]

When it is a good buy

Store snapshots, new in the US (October 2026):

Acme Tools: $269.00-$299.00 [3]
Ohio Power Tool: $329.00 [9]
ToolUp: $365.00 [10]
Burns Tools: $365.00 [12]
PowerHouse Tool Supply: $365.00 listed against a $399.00 MSRP [11]
A deal aggregator showed $269.00 against a $365.00 reference [15]

Pro Tool Reviews reported $279 in 2019 [2]. Outlier listings at $117.00 and $449.49-$566.99 look like drop-ship or marketing noise and should not anchor a decision [13][14]. At the $269-329 end the 5 in. tool undercuts its own 6 in. sibling on price; at $365 it is hard to justify without the sibling’s larger pad and orbit.

Alternatives:

Bosch GET75-6N (6 in. sibling) — the better choice when pace and coverage come first: its 0.18 in (4.5 mm) orbit removes stock faster, while the GET65-5N is the control and consistency pick. [4]
Festool RO 125 FEQ — the better choice when the tool must stay manageable with a dust setup attached, per an owner refinishing stairs who compared the two. [5]
