How to choose a screwdriver: SL, PH, PZ and 1000 V

Buying advice 19/10/2026 By INVENTĀRS 3 views 0 reviews

The wrong profile strips a head faster than “weak torque”. This guide helps you pick one blade, a bit handle or a 1000 V set. PH/PZ/TX bits: bits. Stripping and crimp: electrician tools.

What it is	When	What it is not
Fixed SL / PH blade	One size, every day	A set “because the box is full”
Interchangeable bits	PH, PZ, Torx in one handle	A 1000 V set if the card has no 1000 V
1000 V / insulated set	When the card says 1000 V	A permit to work live
Tester screwdriver	Indication, not tightening	A VDE tool

Pro'sKit 9SD-201B — Pro-Soft, 3.0 × 75 mm. 3.0 mm is blade width, 75 mm length. It is not PH2. 9SD-201A shares the size — read the profile on the card.

Pro'sKit SD-9814 — interchangeable bits. SD-9802 — 31 pcs. SD-9821 — 16-in-1 with ratchets. A ratchet is not 1/2" socket torque.

Pro'sKit SD-9608 — 30-pc precision aluminium set. SD-081A — 7 pcs for electronics. Precision blades are not for an 8 mm wood screw.

Pro'sKit 8PK-8100E — insulated set, 1000 V on the card. The mark is insulation as declared, not live work. LBN p.55 — certified specialist. RICHMANN 42-C5266 — tester 190 mm. A tester is not a 1000 V set and not a commissioning meter.

Before buying: SL/PH/PZ, millimetres, 1000 V or not. Screwdrivers. Sets: screwdriver sets. Bits: bits.
