Bosch GET75-6N: problems, parts and running costs

Checked: 2026-10-17

Summary

Owner reports center on intermittent electrical faults, abrasive discs tearing or crumpling, and dust left on the workpiece even with an extractor attached. A carbon-brush motor means real service items: brushes, bearings and pads, with abrasives the biggest variable cost at about $0.90 per disc. Below $295 new from an authorized shop it is very attractive for two-mode sanding; at $389 it is hard to justify against the Makita BO6050J or the smaller Bosch GET65-5N.

Common problems and fixes

Intermittent electrical startup or sputtering — a November 2025 r/woodworking owner used their GET75-6 for about three years, then it began sputtering and sometimes ran only when the lower housing was squeezed, with suspected visible arcing; possible causes include a bad wire or connector, failed switch, brush/commutator wear or the control board, but no diagnosis was published. Unplug a sputtering unit, do not squeeze the energized enclosure to make it work, check the cord externally and request Bosch authorized diagnosis. [18]
Abrasive discs crumple and tear — a May 2024 r/Tools owner tore 3M Cubitron net, Diablo and Hercules 6-inch discs before the cutting edges were exhausted, in both modes while sanding narrow clamped 4x4 stock with an extra pad saver; commenters suspected pad-saver compliance, pad condition or technique, and no verified fix was established. Stop if a disc wrinkles or lifts, inspect the hook-and-loop surface and avoid excessive pressure or tilting on narrow edges. [11]
Residual dust on the workpiece — a March 2026 r/woodworking owner using a Festool CT15 extractor still saw noticeable dust on the work surface, including after 3M Xtract abrasives; even premium sanders can require a final vacuum sweep. [12]

Parts and consumables

Carbon-brush set 1 619 P02 870 — $13.05 suggested retail in Bosch’s US service catalog; the manual recommends brush inspection every 2-6 months at an authorized Bosch service center, with replacement based on inspection; labor can exceed the parts cost. [3][2]
RSM6045 6-inch medium multi-hole backing pad — $57.14 at Tony Power Tools, October 2026; the supplied pad and correct default replacement; replace when the hook-and-loop stops retaining sheets or the face becomes uneven or damaged; no fixed interval. [15][1]
RSM6044 6-inch soft pad — $57.38 at Tony Power Tools, October 2026; for contours and fine polishing. [15]
RSM6046 6-inch hard pad — $58.39 at Tony Power Tools, October 2026; for flatter, tougher stock removal. [15]
3M Xtract Cubitron II 710W 6-inch net discs — $44.99 per 50-pack at Rockler, October 2026, about $0.90 per disc; change when the cut slows, the sheet loads or tears, or the hooks fail. [17]
Speed governor 1 607 233 5CP — $49.33 suggested retail in Bosch’s US service catalog; replace only after a diagnosed speed-control fault. [3]
Armature 1 607 000 DD6 — $61.61 suggested retail in Bosch’s US service catalog, for the 100-115V US version; not a user consumable, and labor and shipping are extra. [3]
Housing assembly 1 607 000 DC3 — $44.62 suggested retail in Bosch’s US service catalog. [3]
Suction hood 1 607 000 DC4 — $82.11 suggested retail in Bosch’s US service catalog. [3]

Yearly running cost

No batteries, subscriptions or apps; ongoing costs are electricity, abrasives, pad wear, extractor bags or filters, and occasional brush, bearing or gear maintenance. [1][2][3]

Electricity (illustrative, not measured): at an assumed 600W average draw and $0.20 per kWh, sanding 3 hours a week for 52 weeks (156 hours) uses 93.6 kWh, about $18.72 a year; a lighter 25 hours a year uses about 15 kWh, about $3.00. [1][2]
Abrasives: at $0.90 per disc, an occasional user burning 25 discs a year spends about $22.50; a professional burning 200 a year spends about $180. [17]
Pads: if a $57.14 RSM6045 is needed every second year, that averages $28.57 a year; no reliable average pad lifetime was found. [15]
Extractor consumables: dust-bag and filter costs depend on the separately purchased vacuum, so no annual total can be attributed to the sander alone. [1][12]

When it is a good buy

Home Depot listed the GET75-6N at $322.10, and at $318.75 on a different crawl of the same page, in October 2026; Tool Nut and Toolup listed it at $389 in October 2026. [8][9][20] Below $295 new from an authorized shop is very attractive for a two-mode Bosch; $295-330 is good or fair against the Home Depot offer; $331-370 is increasingly weak; at $389 compare the Makita BO6050J or wait for a Bosch promotion, and consider the $299 GET65-5N for smaller jobs. [8][9][13][14][21]

Named alternatives:

Bosch GET65-5N — $299 at Home Depot, October 2026; the 5-inch dual-mode, better for smaller panels and a narrower, lighter pad. [13]
Bosch GEX34-6N — $253.62 at Home Depot, October 2026; 6-inch conventional random orbit only, the better buy when geared turbo is unnecessary. [14]
Makita BO6050J — $459 at Home Depot, October 2026; another 6-inch two-mode forced-rotation sander, the closer functional competitor if the Bosch is $389. [21]
