QPM delivers value over the life cycle of the productLowered costs on materials and labor. Reduced times for setup, fastening, rework, and maintenance. Increased
quality, productivity, ergonomics, and flexibility. Compared to pneumatic and other DC electric assembly tools, QPM is
THE COMPLETE TIGHTENING SOLUTION that delivers lifetime value.
QPM Cables minimize downtime and reduce cost
Cables are typically the weak point in most DC electric tool systems.
But not with the QPM product line, where Stanley engineers have
designed a special high-flex cable that offers a dramatic
improvement in life expectancy over competitive products on the
market.
Using Stanley’s QPM cable reduces the total life cycle cost of a tool installation by reducing the downtime associated
with cable failure as well as the significant investment in replacement cable assemblies required.

Actual Customer … using Atlas Copco
Cable Consumption = 27% fail each year50% of cables replaced and 50% repaired
Cable Replacement450 tools * 27% * 50% * $800 cable cost = $048,600
Cable Repair450 tools * 27% * 50% * $400 repair fee = $024,300
= $072,900 (1 year)
= $364,500 (5 years)

Total Cost of Ownership
QPM Motors and Gears offer maximum power and durabilityStanley’s modular motor and gearing components help QPM systems deliver lower Total Cost of
Ownership. High component durability, predictable life, flexible interfacing, and serviceability
reduce life cycle cost by increasing Mean Time Between Failures (MTFB) and reducing Mean
Time To Repair (MTTR).
Stanley’s patented Adaptive Tightening Control technology gives
more consistent torque results by automatically adjusting for
different joint rates. Pneumatic and other DC electric tools require
either operator-dependant parameter selection or additional tools to
get consistent torque results. ATC also provides cycle time
reductions, extended gear life, and improved ergonomics.
• Spare parts guaranteed for the life of a program
• Preventative Maintenance scheduling
• Preventative Maintenance kit management
• Full service pickup and delivery
• Full service onsite system management

Angle Heads are repairable
and require no special tools.
New Zerol® gears will extend
bevel gear life even further
than before.

Stanley EA-series migrating to Zerol® styleAtlas Copco ST-series using Spiral style
Compatibility
Stanley Zerol® angle heads will accept old style bevelsAtlas Copco spiral angle heads will NOT accept old style bevels
Major Cost Advantage
Atlas Copco brags about their very expensive machine for matching bevel gear sets and adjusting them into alignment.In reality this only renders their bevel gears non-field-repairable by end users in order to FORCE them to buy whole heads.

Comparison Worksheet
Tool #1 … Competitor System
Tool #2 … Stanley QPM System
Aggressive Assumption #1 … Acquisition cost 2X the competitor toolAggressive Assumption #2 … Same number of tool repair eventsAggressive Assumption #3 … Same parts and labor cost(Assumptions are aggressive because, aside from the fact that QPM is not 2X the competitor in terms of acquisition cost, QPM offers advantages in all maintenance categories)
Tool #2 with proactive preventative maintenance
All the same assumptions as above, even the same number of repair events, just planned rather than inflicted.In reality, with proactive maintenance adding a little labor, QPM tools will require fewer repair events and consume fewer parts.However, parts are not significant and labor does not even register on the G Chart as the downtime from CABLES ALONE overwhelms them.
