Long twist drill bit for metal by Tvardy, made of HSS and specified to DIN1869. Diameter 12.0 mm, overall length 375 mm.

## Long description

Long twist drill bit for metal by Tvardy, made of high-speed steel (HSS) and manufactured to DIN 1869 standard. This 12.0 mm diameter drill with an overall length of 375 mm is designed for drilling steel and other ferrous materials where extended reach is required. Supplied in multiple pack sizes, the bit is suitable for both hand-held and machine drilling applications and offers the rigidity and heat resistance typical of HSS tools.
Advantages
The HSS construction provides good wear resistance and retains cutting hardness at elevated temperatures encountered during metal drilling. The long length (375 mm) enables deep-hole drilling and access to recessed areas without the need for extensions or special tooling. Conformance to DIN 1869 ensures consistent geometry and performance for professional and workshop use. The 12.0 mm diameter delivers a balance between hole size and axial stiffness for controlled drilling in ferrous materials.
Suitable for
 Drilling through steel plates, beams and profiles
 Creating deep or recessed holes in metal assemblies
 Use with portable drills and drill presses where extended reach is needed
 General fabrication, maintenance and repair tasks on ferrous materials
Key specifications
 Material: High-speed steel (HSS)
 Standard: DIN 1869
 Diameter: 12.0 mm
 Overall length: 375 mm
 Intended material: Steel and other ferrous metals
 Shank type: straight (suitable for standard chucks)
How to use
Secure the drill bit in a properly rated drill chuck and ensure it is tightened to prevent slipping. Mark and center-punch the drilling location to reduce walking. Start drilling at low speed to establish the hole, then increase speed according to the material and drill diameter while maintaining steady feed pressure. Use cutting fluid or coolant when drilling steel to reduce heat build-up and extend tool life. Periodically withdraw the bit to clear chips during deep-hole drilling.
Usage recommendations
For best results, match drill speed and feed to the 12.0 mm diameter and the grade of steel being machined; apply appropriate cutting fluid and avoid excessive side loads to preserve tip geometry and prevent breakage of the long HSS bit.
