Precision screwdriver and bit sets for electronics, phone, watch and camera repair · bit profiles and sizes (Phillips PH000–PH1, Torx T1–T10, Pentalobe P2, Tri-point Y), bit steel and HRC hardness, 4 mm bit sockets, magnetic holders, ESD-safe handle resistance, ISO 8764-1 and ISO 2380-1 tip standards
A precision screwdriver set is a group of small fixed-blade screwdrivers, or one slim handle with interchangeable 4 mm bits, used to open and reassemble phones, laptops, game consoles, watches, glasses and cameras. Ask three things first: which screw profiles and sizes your devices use, including security types such as Pentalobe and Tri-point; what steel and hardness the bits are made of and how the tips are machined; and whether the handles must be ESD-safe for work on electronic assemblies.
Precision screwdriver sets and precision bit kits for electronics, phone, computer, watch, eyewear and camera repair, including fixed-blade precision drivers, 4 mm bit sets with magnetic holders and ESD-safe precision sets. Full-size screwdrivers, 1/4-inch power bits, insulated VDE electrician's screwdrivers, torque screwdrivers and automatic screw-fastening machines are outside this page except where compared.

iFixit's Mako Driver Kit contains 64 precision bits for a 4 mm driver, including Phillips #000, #00, #0, #1 and #2; flathead 1.0 to 4.0 mm; Torx T2 to T5 and Torx Security TR6 to TR25; Pentalobe P2, P5 and P6; Tri-point Y000, Y00, Y0 and Y1; JIS 000 to 1; hex 0.7 to 5.0 mm; and Gamebit, oval, spanner, square and triangle bits. A 28-bit Hoto set listed by Modulor holds Phillips PH000, PH00, PH0 and PH1; slotted SL1.5 to SL3; Torx T1 to T4; Torx Security T5H, T6H, T8H, T9H and T10H, which the listing says also fit plain Torx; Pentalobe P2, P5 and P6 for iPhone and MacBook; Y0.6; and hex 1.5 to 2.5 mm. [1][3]
Fixed-blade sets cover fewer profiles: Wiha's 7-piece ESD-safe PicoFinish set holds slotted 1.5 × 40, 2.0 × 40, 2.5 × 50 and 3.5 × 60 mm and Phillips #00 × 40, #0 × 50 and #1 × 60 mm. [2]
ISO 8764-1:2004 specifies the shapes, dimensions, technical requirements and torque test methods for the tips of hand drivers and machine bits for cross-recessed screws, in two forms: PH for form H recesses and PZ for form Z recesses. ISO 2380-1:2004 specifies the form, dimensions and designation of tips for slotted-head screws and, for hand screwdrivers, the test torque the blade-to-handle connection must withstand. ISO lists both as last reviewed and confirmed in 2024. [4][5]
Editorial note: Phillips (PH), Pozidriv (PZ) and JIS cross tips are different profiles, so list each one separately in the order, and ask the supplier to mark the profile and size on each bit or cap.
Give the supplier the devices or screw list to be served, each profile and size (Phillips, Pozidriv, JIS, slotted, Torx, Torx Security, Pentalobe, Tri-point, hex and others), bit shank size and length, bit steel and hardness, handle type and whether ESD-safe, magnetic holder, case and labelling, and quantity.

Compare bit steel, hardness, handle and ESD protection
iFixit specifies S2 steel bits, an anodised aluminium driver with a magnetic bit socket, knurled grip and swivel top, an EVA foam insert and an ABS case of 17.8 × 10.9 × 3.8 cm; it lists 6150 steel for the 1/4-inch bits in another of its kits. Modulor's Hoto listing gives S2 steel bits at 60 HRC hardness, a magnetic aluminium 4 mm holder with a freely turning cap, and a magnetic case with labelled bits and compartments. [1][3]
Wiha states that its ESD-safe PicoFinish drivers meet IEC 61340-5-1 for protecting electronic devices from electrostatic discharge, with a handle surface resistance of 10^6 to 10^9 ohms. The drivers use Wiha tool steel with a chrome-plated satin finish for corrosion protection, precision-machined tips to reduce cam-out, a hex finger grip, an extra-long cap, dual-durometer handles moulded directly to the blade, and the tip profile labelled on the cap. [2]
Editorial note: ESD-safe handles are specified by surface resistance, not by a voltage rating; Wiha lists insulated screwdrivers as a separate category. Ask for the hardness test method and value for the bit tips, not only the steel grade.
03
From a 7-blade ESD set to a 64-bit kit
Reviewed sets range from fixed-blade ESD-safe drivers with 7 blades to bit kits with one 4 mm handle and 28 or 64 bits. When requesting quotations, ask each supplier for the full bit list with sizes, bit steel and hardness, handle material and ESD data, and a sample set.
04
Bits, tip forms, handle, finish and case
The ESD row applies to fixed-blade handles such as Wiha's; the magnetic 4 mm socket and swivel top belong to bit-kit drivers like iFixit's. [2][1]

Piece count, tip range, hardness and handle data to request
Hardness is the one field here with a direct published value (60 HRC on S2 steel); handle diameter, overall length and weight have to be measured on a sample or taken from the supplier. [3]

Buyer questions
Which bits open phones and laptops with security screws?
iFixit's 64-bit Mako kit includes Pentalobe P2, P5 and P6, Tri-point Y000–Y1 and Torx Security TR6–TR25 alongside Phillips #000–#2. [1]
How hard are precision screwdriver bits?
A 28-bit Hoto set listed by Modulor gives S2 steel bits at 60 HRC; ask each supplier for the HRC value and test method. [3]
What makes a precision screwdriver ESD-safe?
Wiha's ESD-safe drivers meet IEC 61340-5-1 with a handle surface resistance of 10^6 to 10^9 ohms. [2]
Sources and what still needs a direct check
Sources checked 2026-10-11. Two maker product pages, a retailer listing of a bit set, and two ISO standard abstracts; values for your set must come from the supplier's specification and samples.
