Screwdrivers Haisser

Haisser: precise driving without extra weight

How a screwdriver differs from a drill-driver

A screwdriver is a simpler, lighter tool than a drill-driver, optimized specifically for driving fasteners: no impact mechanism for drilling hard materials, but lower weight and a longer chuck life under constant contact with screws. For work where drilling isn't needed at all — drywall installation, furniture assembly, roofing — that makes it the more rational choice over a heavier, more versatile drill-driver.

The Haisser line-up in this category

Haisser's range in this category has four cordless models. The impact CD-245H (400/1500 rpm) and CD-260HBC (500/1800 rpm) add an impulse mechanism for driving into dense or unprepared material where plain torque isn't enough. The non-impact CD-260BC (500/1800 rpm) and CD-L0418 (400/1500 rpm) are built for softer materials — wood, chipboard, drywall — where an impact pulse isn't needed and can even be harmful, since it can damage the surface around a fastener or split thin material.

The power difference between models directly affects the size of screw the tool handles comfortably: the entry-level CD-245H and CD-L0418 handle typical drywall screws and small furniture fasteners well, while the more powerful CD-260HBC and CD-260BC hold up to regular driving of longer screws into denser materials without overloading the gearbox and motor.

All four models run on a cordless platform with a quick-clamp bit holder that lets you swap accessories without a wrench in seconds. Electronic trigger-based speed control provides the smooth start needed to position a screw precisely before the main drive — a detail that directly affects the finish quality on visible fasteners, such as on facade panels or furniture fronts.

Impact mechanism and driving precision

The preset torque clutch, present on every model in the range, lets you lock in the needed force once and then drive dozens or hundreds of screws at a consistent seating depth without manually checking each one. That's especially valuable in high-volume installation, where even a few millimeters of variance in seating depth affects the look of the finished surface.

The choice between impact and non-impact comes down to the dominant material: if the work leans toward driving into dense or unprepared materials, the impact version saves time and reduces chuck wear, while if the main load is soft materials like drywall or timber, the non-impact model gives finer control and less risk of surface damage. Mixed workloads, where one person handles both types of jobs across a week, often justify owning both — a light non-impact model for finish work and an impact one for rough-in — rather than compromising on a single model for everything.

Ergonomics, service life, and how to choose

Screwdriver ergonomics are shaped for monotonous, repetitive work rather than short bursts of drilling: the housing is lighter than a comparably powered drill-driver, the center of gravity sits closer to the palm, and rubberized grip inserts cut slippage during extended hold. For roofers and installers holding a tool for hours at a stretch, a difference of a few hundred grams per shift adds up to noticeably less wrist fatigue.

Screwdriver service life depends mainly on the durability of the chuck and the trigger's contact assembly — the components that see the most actuation cycles per working day. Haisser models in this category use reinforced contact assemblies rated for regular load, which directly extends tool life compared to the cheapest market alternatives, where similar parts often fail within the first active season.

A battery shared across the CD-series also means a crew can standardize on one charging system rather than juggling several incompatible packs, which cuts downtime waiting on chargers and simplifies keeping spares on hand during a busy shift.

Pick a Haisser screwdriver by impact mechanism, power and speed to match the materials typical of your project, and driving fasteners stops being the slowest, most tiring part of daily work, whether at home or on a job site.
