## Long description

The Yato YT-44757 4 mm twist drill bit is designed for precise round-hole drilling across a range of common materials. Supplied as a single piece, this drill bit delivers a consistent cutting geometry and a compact 4 mm diameter that is suitable for small holes and pilot drilling.

Advantages
This 4 mm twist drill bit offers accurate centring and steady chip removal thanks to its standard twist-flute geometry. The solid construction provides useful wear resistance during routine domestic and workshop tasks while maintaining the small-diameter rigidity required for clean holes. Because it is a single, ready-to-use unit, it is convenient to replace or carry as a spare in a tool kit.

General workshop maintenance and repair tasks
Key specifications
Drill type: twist drill bit
Diameter: 4 mm
Package quantity: 1 piece
Compatibility: standard drill chucks for handheld and bench drills

How to use
Select the appropriate drill speed and clamp the workpiece securely before drilling. Fit the 4 mm twist drill into the drill chuck and tighten firmly. For metal and harder materials, start at low speed and apply steady feed pressure; for wood and plastics, a moderate to high speed with light pressure provides cleaner holes. Withdraw periodically to clear chips when drilling deeper holes. Wear appropriate eye protection and follow safety practices for rotating tools.
Usage recommendations
For longer tool life when working with metal, use a suitable cutting fluid and avoid excessive side pressure. For precise positioning, mark the center with a punch before drilling. Store the bit in a dry tool case to prevent corrosion and maintain tip condition.
