Hangzhou Xinabo Intelligent Electromechanical Technology Co., Ltd manufactures pipe fabrication equipment and the Xiaojia cordless tool range that crews carry alongside it. The XJ.608 21V Lithium-Ion Brushless Hammer Drill/Driver — 100N·m Torque, Anti-Kickback Control is the general-purpose unit in that line: a 13mm-chuck, two-speed, hammer-capable driver for fixing, first fix and light construction work.
We supply it as a working kit — tool, 21V battery, charger, side handle and bit set — and set the kit composition around the crew's material mix, shift length and the battery platform already held in the site store.
Where the XJ.608 Fits on Site
Most of a fixing crew's day is spent making holes and driving fasteners before pipe, conduit or cable tray goes up. The XJ.608 covers that front-end work in one body: drill mode for timber, metal and plastics, hammer mode for brick and block, and enough torque to seat structural screws without stalling.
- Installation and fixing — anchor and bracket holes, hanger and support fixing, conduit and cable tray mounting.
- Light construction and renovation — timber drilling, sheet-metal hole work, plumbing and electrical first fix.
- Assembly and maintenance — equipment and furniture assembly, screw fastening, fixture and appliance repair.
- Outdoor and yard work — frame and fence assembly, equipment fixing, gear installation.
Above it in the range sit the XJ.615 at 140N·m and the XJ.617 at 170N·m with three speeds. The XJ.608 is the tool we put in the hands of general installation crews and maintenance teams who need one cordless driver to cover several trades.

Reading Torque, Speed and Chuck Size for Your Application
Two-speed gearing
Low gear at 0–400 rpm trades speed for turning force, which is where hole saws in sheet metal, auger bits and long timber screws belong. High gear at 0–1800 rpm suits 3–8mm twist drills in steel, pilot holes and small masonry work where cycle time matters more than leverage.
The 13mm keyless chuck
A 13mm keyless chuck covers the majority of installation tooling: twist drills, brad-point bits, hex-shank drivers, hole saws on their arbors and masonry bits. Shanks above 13mm, or SDS-plus tooling, need a different machine — our rotary hammer range takes SDS-plus directly.
Hammer mode boundaries
Hammer mode drives the bit against brick, block and soft masonry, and is the right setting for a handful of anchor holes in a wall. For repeated holes in cured concrete, anchor setting to depth or any chiselling, a rotary hammer does the work faster and with less wear: the XJ.709 delivers 1.7J and the XJ.728 delivers 2.8J through an SDS-plus chuck. The hammer drill's ratchet mechanism is built for occasional masonry, not production concrete drilling.
Anti-Kickback Control and Operator Safety
When a bit jams — a hole saw catching in sheet metal, a twist drill breaking through steel — the tool body kicks back. The XJ.608 carries a gyroscopic anti-kickback function that senses the sudden rotation and cuts the reaction force, so the wrist and forearm take far less of the load. It operates without setup or operator input.
- Fit the side handle and use both hands whenever the work is overhead or the bit is above 8mm.
- One-touch forward/reverse keeps direction changes quick during assembly and when backing out a fastener.
- The anti-slip handle and balanced body help keep the bit aligned during overhead drilling.
- Clamp or otherwise secure the workpiece; anti-kickback reduces the effect of a bind but does not replace workholding.
Battery, Charger and Platform Compatibility
Every tool in the Xiaojia 21V line — angle grinder, circular saw, rotary hammer, impact wrench, hole puncher, spray gun — runs on the same pack, so a site store carries one battery type and one charger family. The XJ.608 kit ships with a battery and charger; charger plug type and input voltage are confirmed against the destination market when the order is placed.
For crews working a full shift away from a socket, the Backpack Lithium Battery Pack — 20Ah/30Ah, Powers Multiple 21V-60V Tools Simultaneously extends runtime across the platform without changing tools.
Choosing Within the Cordless Hammer Drill/Driver Range
We manufacture the Xiaojia 21V cordless line in Hangzhou, China, and the three hammer drill/drivers differ mainly in torque ceiling and gearing. Matching the model to the fastener schedule avoids carrying more tool than the work needs.
Factory Quality Control and Documentation
Xinabo has been building power tools and pipe equipment in Hangzhou since 2010. Our 10,000 m² plant operates with more than 100 staff, and the company holds National High-tech Enterprise status with a portfolio of 30 patents covering threading, clamping and pipe-processing mechanisms. The published finished-product rate for our production is 99.9%.
Quality control runs from incoming material inspection through motor and gearbox assembly to finished-product function checks. Attestation of conformity under the Machinery Directive and EMC Directive forms part of our certification portfolio. Tools are labelled by model, and each shipment leaves with a packing list and accessory schedule that match the confirmed order.
Installation, Acceptance and Maintenance
Handover checks take a few minutes per tool and settle most early warranty questions before the crew leaves the store.
- Charge the battery fully, fit the side handle and confirm the chuck jaws close squarely on a test bit.
- Run each gear unloaded for about 30 seconds and listen for abnormal noise or vibration.
- Test hammer mode on a scrap block, then check forward and reverse under light load.
- Confirm the anti-kickback response with a controlled bind on scrap timber at low speed.
- Record serial numbers against the delivery note so spare-part and battery orders can be traced later.
The brushless motor removes brush service from the maintenance schedule. Keep the ventilation slots clear of dust, inspect the chuck jaws for wear, and replace chucks, side handles and battery packs from our spare-parts stock when they reach end of life. Store packs charged and dry, and rotate them across the crew rather than leaving one pack in constant use.
Information We Use to Configure Your Solution
We build the quotation from the work rather than from a catalogue number alone. These inputs let us fix kit composition, accessory set and documentation in one pass.
- Material and fastener schedule — timber, steel, masonry or mixed, with screw and anchor sizes.
- Hole range — typical diameters and depths, and whether hole saws are involved.
- Duty cycle — holes or fasteners per shift, and how many crews share the tools.
- Platform position — which 21V tools and packs are already in the fleet.
- Kit split — tools, batteries and chargers per set, and whether single-tool or multi-tool kits are needed.
- Market requirements — charger plug type, input voltage, label language and packaging format.
- Support scope — demonstration, operator briefing and documentation language for the handover.
Frequently Asked Questions
What does the 100N·m rating mean in practice?
It is the maximum turning force the tool can deliver, and it is reached in low gear. On site that translates into seating long timber screws, driving hex-shank fasteners into pre-drilled steel and turning hole saws through sheet metal without the motor stalling on every cut.
Can the XJ.608 drill into concrete?
It has a hammer mode and handles brick, block, mortar joints and light masonry, which covers occasional anchor holes in a wall. For repeated drilling in cured concrete, deep anchor setting or chiselling, we recommend the XJ.709 or XJ.728 rotary hammer, which use SDS-plus tooling and a dedicated impact mechanism.
Does the kit include a battery and charger?
Yes. The standard kit contains the tool, a 21V battery, a charger, a side handle and a drill/bit set. Charger plug type and input voltage are matched to the destination market when the order is confirmed.
Is the anti-kickback function automatic?
It is. A gyroscopic sensor detects the sudden body rotation that occurs when a bit binds and reduces the reaction force without any setting, switch or operator action. The side handle should still be fitted for high-torque work.
Do the batteries fit other Xinabo tools?
The 21V pack is shared across the Xiaojia cordless range, including the angle grinder, circular saw, rotary hammer, impact wrenches, hole puncher and spray gun. A site can standardise on one pack type and add the backpack battery pack where longer runtime is needed.
How is the kit composition agreed for a project?
We work from the material and fastener schedule, the hole range, the duty cycle and the tools already in the fleet, then confirm the split of tools, batteries and chargers per set together with label language, packaging and handover documentation.
