Brushless Cordless Hammer Drill Set — 21V with 2 Batteries, 87 Accessories and 10mm Heavy-Duty Chuck (KELNOW)
Product description
What it is
This is a 21V brushless cordless hammer drill set from KELNOW, designed for DIY tasks around the home. It combines a compact brushless motor with a two-battery system, a 10mm heavy‑duty chuck and a broad accessory kit. On paper, the aim is straightforward: more power, longer life and fewer sparks than typical brushed drills, all in a package that’s approachable for non‑pros.
What matters most
The absence of brushes can translate to better efficiency and less heat buildup during use, with a stated maximum torque of 60Nm. The drill offers 25 + 3 torque settings across two speeds, which allows you to tailor output for wood, metal, plastic or masonry tasks. The dual‑battery design is meant to minimise downtime, while a built‑in LED helps illuminate work areas, and the fast‑charge capability targets shorter breaks between sessions.

Technical overview
Key specs (as provided) include 21V power, 60Nm max torque, 2 speed settings, 25 + 3 torque control, a 10mm heavy‑duty self‑locking chuck, and an 87‑piece accessory kit. The set includes drill bits for wood and masonry, a selection of screwdriver bits, sockets, a flexible shaft, and a socket adapter, all intended to cover common DIY scenarios from hanging shelves to light masonry tasks.
What you’ll notice in use


In practice, you may appreciate the rapid readiness from two high‑capacity batteries and the light emitted by the LED for darker corners. The 10mm chuck should offer decent bit retention for routine drilling and screwdriving, while the two‑speed control helps with progressive driving and drilling. If you’re working in tight spaces or overhead, the compact form and brushless efficiency can be a real help.

Pros and cons
Pros: brushless motor for efficiency and potential battery life gains, dual batteries to reduce downtime, broad accessory kit provides ready‑to‑go versatility, LED light aids working in dim spaces. Cons: the information available doesn’t specify individual battery capacity or run‑time per task, and no explicit warranty details are provided here.
Who it’s for
This set is well suited to homeowners and hobbyists who want a complete kit for general DIY tasks—drilling into wood, metal, plastic and masonry, plus driving screws. It’s a sensible choice if you value a bundled kit with many accessories and two batteries to limit pauses for charging.

When it makes sense to buy
Consider this kit if you anticipate a mix of drilling and driving tasks around the home and you prefer having two batteries on hand. It’s particularly practical if you want a compact, brushless solution with a sizeable accessory set without buying bits separately.


When it might not be the best choice
If you need long run‑times for heavy masonry or professional, daily‑use workloads, or you want precise torque readouts for demanding tasks, this kind of kit may feel under‑powered relative to higher‑end options. The lack of detailed battery specifications and warranty information means you should check those details before purchase.

What to check before buying
Look for the actual battery capacity and the throw of the two batteries under load, plus how quickly the charger can restore charge. Inspect the chuck for smooth operation and consider whether the included 87 accessories align with your typical DIY tasks. Think about whether you’ll rely on the LED light in your usual work environments and how comfortable the tool feels in your hand during longer sessions.
Practical usage example
Imagine mounting a new shelf in a dim garage. With the LED on, you’ll spot pilot holes more easily. Drill into a mix of pine and drywall, then switch to screwdriver bits to secure brackets. The two batteries mean you can pause to swap a fresh pack without losing momentum, while the heavy‑duty chuck keeps the bits aligned as you drive screws at a steady pace.

What’s included and in the box


The kit comes with two high‑capacity batteries, a fast charger, and an expansive 87‑piece accessory set that includes wood and masonry drill bits, screwdriver bits, sockets, a socket adapter, a flexible shaft, and a 10mm metal heavy‑duty chuck. This breadth of bits aims to cover many everyday tasks without hunting for extras.
Final verdict
Final take: on the surface, this is a practical, well‑rounded DIY kit that emphasises convenience and usability through a brushless motor, two batteries, and a broad accessory set. It may be a solid mid‑range choice if you prioritise a complete bundle and value a compact, low‑spark tool for home tasks. It might not be the best option if you require heavy‑duty, professional‑grade performance or detailed battery specs.

FAQ
- How many batteries does it include? Two high‑capacity batteries are included.
- Is it suitable for masonry drilling? The kit includes masonry bits, but real performance depends on your tasks and the drill’s torque under load.
- Does it come with a warranty? Warranty details aren’t specified in the information provided.
Final thought
If you prioritise having a comprehensive starter kit with a brushless motor and two batteries for routine DIY tasks, this set offers a pragmatic combination. It’s worth comparing the battery life and charger speed once you know the exact capacity and warranty terms.
