Bauer Tools 1702C-B 20V Cordless Drill/Driver
Our 1702C-B cordless drill/driver combines compact design with serious drilling power for professionals and DIY enthusiasts. This 20-volt brushless motor tool delivers 350 in-lbs of torque with precise variable speed control from 0-400 and 0-1,500 RPM, making it ideal for drilling into wood, metal, and plastics or driving fasteners of all sizes.
The 1/2-inch keyless chuck accepts standard drill bits and driver bits, while the 24-position clutch gives you exact torque control to prevent overdriving screws or stripping materials. We designed the ergonomic soft-grip handle to reduce fatigue during extended use, and the built-in LED work light illuminates dark corners and overhead tasks. The compact 7.5-inch length fits into tight spaces where larger drills can’t reach.

Motor Performance & Power Delivery
The brushless motor in the 1702C-B operates at higher efficiency than traditional brushed motors, delivering consistent power throughout the entire battery charge cycle. You’ll notice less heat generation and significantly longer runtime per charge compared to older drill technologies.
Our dual-speed transmission switches between 0-400 RPM for high-torque driving applications and 0-1,500 RPM for fast drilling through various materials. The electronic brake stops the chuck immediately when you release the trigger, preventing accidental overdriving and giving you precise control over every fastener. This same power platform extends across our entire cordless tool lineup, ensuring consistent performance across your toolbox.
Chuck System & Bit Compatibility
Quick-Change Keyless Chuck
The 1/2-inch keyless chuck on the 1702C-B accepts any standard round or hex-shank bit from 1/32-inch up to 1/2-inch diameter. The single-sleeve design allows one-handed bit changes in seconds—simply grip the chuck sleeve, rotate to loosen, insert your bit, and tighten with a quick twist.
We machined the internal jaws from hardened steel to maintain secure bit retention even under high-torque applications. The chuck grips hex-shank driver bits, twist drill bits, spade bits, hole saws, and specialty attachments without slipping. For maximum versatility, the 24-position adjustable clutch ring surrounds the chuck, giving you numbered settings plus a dedicated drill mode for full power.
Battery System & Runtime
The 1702C-B operates on any Bauer 20V lithium-ion battery pack from 1.5Ah up to 4.0Ah capacity. We designed the battery interface with our slide-pack mounting system that locks batteries securely in place while allowing tool-free removal with the side release buttons.
Typical runtime with a 2.0Ah battery includes approximately 400 deck screws (3-inch) on a single charge, or drilling up to 50 holes (1-inch diameter) through 2×4 lumber. The onboard battery fuel gauge shows remaining charge at a glance with three LED indicators. Our 20V battery packs charge in 30-60 minutes depending on capacity, and the battery management system protects cells from over-discharge, over-temperature, and overcharge conditions.

What people are saying
Common Questions About the 1702C-B Drill/Driver
The 1702C-B works with any Bauer 20V lithium battery from 1.5Ah to 4.0Ah capacity. For occasional DIY use, a 2.0Ah battery provides 2-3 hours of intermittent drilling and driving. Professional contractors typically prefer 4.0Ah batteries for all-day runtime without mid-shift charging.
The drill’s power output remains consistent across all battery sizes—larger capacities simply extend your working time between charges. We recommend owning at least two batteries so one charges while you work with the other.
Yes, the 1702C-B drills through sheet metal, aluminum, and mild steel up to 1/4-inch thick when equipped with appropriate HSS or cobalt drill bits. The dual-speed gearbox delivers sufficient torque for metal drilling at the lower 0-400 RPM setting.
For masonry and concrete, we recommend upgrading to our 1781C-B hammer drill model, which adds percussive action specifically designed for masonry materials. While the 1702C-B can drill small pilot holes in brick with masonry bits, it lacks the hammer function for efficient concrete work.
Rotate the numbered collar ring surrounding the chuck to select clutch positions 1-24, with lower numbers providing less torque and higher numbers delivering more driving power. For driving small brass or finish screws, start around position 5-8 and adjust upward if needed.
For 3-inch deck screws or lag bolts, use positions 18-24 for maximum torque. The drill icon setting bypasses the clutch entirely, delivering full motor power for drilling applications. The clutch disengages with a distinctive clicking sound when it reaches the set torque limit.
All Bauer 20V lithium batteries interchange across our entire cordless tool platform, including impact drivers, circular saws, reciprocating saws, and work lights. One battery system powers your complete workshop, eliminating the need for multiple charger types.
The slide-pack battery mount is standardized across all Bauer 20V tools. Your 1702C-B batteries work in any current or future Bauer 20V tool you add to your collection, providing long-term value and flexibility as you expand your cordless lineup.
The brushless motor in the 1702C-B uses electronic switching instead of physical carbon brushes, resulting in 30-50% longer runtime per battery charge compared to brushed motors. Brushless designs generate less friction heat, allowing higher efficiency and more power delivery to the chuck.
Brushless motors require no brush replacement maintenance and typically last 2-3 times longer than brushed motors under equivalent workloads. You’ll notice consistent power output even as the battery depletes, whereas brushed motors gradually lose torque throughout the discharge cycle.
The integrated LED automatically illuminates when you pull the trigger and remains lit for 20 seconds after you release it. This delay gives you time to inspect your work, reposition for the next hole, or locate your next fastener without repeatedly triggering the drill.
The LED draws minimal power from the battery—approximately 0.5 watts—so the work light has negligible impact on your overall runtime. The bulb is rated for 20,000+ hours of use and requires no replacement under normal operating conditions.
Yes, the 1702C-B works well for automotive applications including removing interior panels, drilling body repairs, and driving self-tapping screws in sheet metal. The compact 7.5-inch length fits under dashboards and into engine compartments where larger drills struggle.
The variable speed control and precise clutch settings prevent overtightening plastic fasteners or stripping threads in aluminum components. For removing rusted bolts or lug nuts, consider pairing the 1702C-B with our 1791C-B1 impact driver, which delivers higher rotational force for stubborn fasteners.
