Compare the BCD702C1 and DCD771C2 by Bit Fit, Controls and Battery Family

Match the bit shank first: the BCD702C1 page lists a 3/8-inch chuck, while the DCD771 manual identifies a 1/2-inch chuck; neither chuck figure is a maximum hole-size rating. For screw driving, compare the BCD’s 11-position clutch and the DCD771’s numbered collar and two gear ranges. The BCD page names one LBXR20 battery and an LCS1620 charger; the DCD manual provides a pack-compatibility chart, but its exact C2 kit contents remain unconfirmed in the accessible manufacturer material.

The buying question

Which kit better fits the bit shanks, screw-driving controls and battery family already planned for the job?

The BCD702C1 has a published 3/8-inch keyless chuck, 11-position clutch and a manufacturer-listed LBXR20 battery/charger kit. The DCD771 tool has a published 1/2-inch chuck, a 1-15 torque collar, two gear ranges and a manual compatibility chart for DEWALT packs. Its accessible official documentation does not establish the exact C2 box contents.

Quick verdict

Choose BLACK+DECKER BCD702C1 20V MAX Drill/Driver Kit if

  • Your intended bit shanks fit the 3/8-inch chuck and you want the BCD702C1 page’s specified one-battery LBXR20 and LCS1620 configuration.
  • The BCD702C1’s 11-position clutch and built-in bit storage fit your screw-driving routine; verify exact seller-box contents if you need a particular bit.

Choose DEWALT DCD771C2 20V MAX Compact Drill/Driver Kit if

  • Your bit shank calls for the DCD771’s 1/2-inch chuck, without treating that dimension as a hole-size rating.
  • You already own a DEWALT pack whose exact model appears in the DCD771 manual’s compatibility chart and want the documented two-range gearing and numbered torque collar.

When to skip: Your actual bit shank is larger than the BCD702C1’s published 3/8-inch chuck and you are considering that model for the job.
When the recommendation changes
  • The actual bit shank requires a different chuck capacity.
  • The buyer owns a battery whose exact model is listed in only one tool’s manufacturer compatibility guidance.
  • The seller’s exact kit contents differ from the listed configuration or must include a particular bit or spare pack.

The differences that matter

Bit And Tool Controls

BLACK+DECKER BCD702C1 20V MAX Drill/Driver Kit

The BCD702C1 US product page lists a 3/8-inch keyless chuck, an 11-position clutch, and built-in driver-bit storage. Its manual documents a variable trigger, forward/reverse control and torque collar for the BCD702 tool body.[1, 2]

DEWALT DCD771C2 20V MAX Compact Drill/Driver Kit

The DCD771 manual identifies a 1/2-inch keyless chuck, a numbered 1-15 torque collar, and two gear ranges; it describes speed 1 as the high-torque setting and speed 2 as the low-torque setting.[3, 4]

What this changes: Start with the actual bit shank and the operation: the documented chuck sizes are a fit check, not a hole-size rating. If the shank fits, choose between the BCD702C1 clutch/storage layout and the DCD771 two-range gearing and numbered collar based on the screw-driving or drilling steps you actually plan. The listed controls do not establish a real-world drilling or fastening winner.[1, 2, 3, 4]

The better fit depends on your priorities

Battery Platform And Kit Fit

BLACK+DECKER BCD702C1 20V MAX Drill/Driver Kit

The exact BCD702C1 US page specifies one 1.5Ah LBXR20 battery and an LCS1620 charger and identifies the drill as part of the 20V MAX POWERCONNECT system. It does not confirm a separate drill bit in its listed Includes section.[1]

DEWALT DCD771C2 20V MAX Compact Drill/Driver Kit

The DCD771C2-linked North American manual lists compatible DEWALT 20V MAX pack models, including DCB201, DCB203 and DCB204, and designated chargers. The opened manufacturer material does not establish how many packs or which accessories are in the exact DCD771C2 kit box.[3]

What this changes: If a battery is already on your shelf, match its exact model to the relevant manufacturer compatibility information before choosing; do not assume that two products labeled 20V MAX share a pack. The BCD page confirms its named one-pack/charger configuration, while the DCD manual helps an existing DEWALT-pack owner check fit but does not settle the C2 bundle contents. Confirm the seller’s exact box list for included bits or spare packs.[1, 3]

The better fit depends on your priorities

Best for your routine

A planned bit shank over 3/8 inch but no larger than the DCD771’s published 1/2-inch chuck dimension

Best fit: DEWALT DCD771C2 20V MAX Compact Drill/Driver Kit

Based on listed features, not comparative testing.

The DCD771 manual specifies a 1/2-inch chuck while the BCD702C1 page specifies 3/8 inch. Check the bit maker’s requirements; this is a chuck-fit distinction, not a drilling-capacity or performance result.

Based on listed features, not comparative testing.

The DCD771 manual names compatible DEWALT pack models. Match the exact pack label to that chart; it does not verify the C2 package count or promise a particular runtime.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Only a verified live offer can be weighed against the chuck fit, control layout, compatible battery already owned and exact box contents the buyer needs; this comparison sets no price threshold.

No purchase-timing call is supported here; recheck the current seller, offer and exact package before purchase.

Limitations

  • Chuck diameter and the manuals’ material-capacity tables answer different questions. The BCD702 table is labeled “Drilling capacity” and the DCD771 table “Maximum Recommended Capacities”; their listed wood and steel entries are not a head-to-head test and do not establish values for other materials or conditions.
  • The BLACK+DECKER manual is a regional multilingual BCD702 tool-body manual linked to BCD702C1; it is used only for operating controls, not the US kit list.
  • The opened DCD771 manuals support tool-body and battery-compatibility facts, not the DCD771C2 box contents; verify the selected package list before purchase.
  • The exact DCD771C2 in-box battery count, charger, bag and included bits remain unverified from accessible manufacturer material. Do not infer the box contents from the C2 suffix or retailer Q&A answers.
  • The BLACK+DECKER product page specifies one LBXR20 pack and LCS1620 charger, but its listed Includes section does not establish whether a separate driver bit is in a given seller package.
  • No cross-brand battery interoperability, runtime, drilling/fastening performance, quality, comfort, reliability or safety winner is established.
  • The observed exact-product retailer questions are qualitative intent signals only; they are not product facts, controlled test evidence, long-term evidence or a measure of current search volume.
  • Confirm the current seller, live offer and exact package before purchase.

Questions shoppers ask

Does a 3/8-inch chuck mean the drill can only make 3/8-inch holes?

No. The 3/8-inch figure is a chuck-size specification, not a hole diameter. In the BCD702 manual, the Technical Data table is labeled “Drilling capacity” and lists 1 inch in wood and 3/8 inch in steel for the BCD702 tool body. The DCD771 manual labels its table “Maximum Recommended Capacities” and lists 1 inch in wood and 1/2 inch in steel. These are separate manufacturer table entries for the named materials, not head-to-head test results; other materials and conditions are not established here.

Will an existing DEWALT battery work with the DCD771?

Check the battery model printed on the pack against the DCD771 manual’s compatibility chart. The manual lists specific DEWALT pack and charger models; do not assume compatibility from the voltage label alone.

Does the BCD702C1 package include a separate drill bit?

The BLACK+DECKER page documents built-in driver-bit storage, but its listed Includes section names the drill, LBXR20 battery and LCS1620 charger without settling separate-bit contents for a seller’s package. Confirm the exact box list before ordering.

How many batteries come in the DCD771C2 box?

The manufacturer material available for this comparison does not establish the DCD771C2 kit’s exact pack count. Check the exact seller package contents rather than inferring it from the model suffix.

Methodology and sources

Compared the exact BCD702C1 US manufacturer page and model-linked manuals for the BCD702 and DCD771 tool bodies. Checked chuck dimensions, the published clutch and gear controls, BCD702C1 named battery/charger details, and the DCD771 manufacturer compatibility chart. Used no retailer answers as product facts. The opened DCD771 manual documents tool and battery compatibility, not DCD771C2 box contents; no package claim was made for that kit. The comparison gives a conditional bit-and-battery fit matrix, not a measured winner.
