## Summary description

The Proline Tools 78105 drill bit features a diameter of 10.5 mm and a length of 133 mm. Designed for metal drilling, it offers precision and durability for various applications.

## Long description

135° point angle with adjustable chamfering enables faster drilling and reduces time spent on marking. Manufactured from high-grade HSS steel containing 5% cobalt, the drill bits offer increased temperature resistance and are suitable for drilling in high-alloy, titanium, acid-resistant, stainless and creep-resistant steels, cast iron (materials with durability above 900 N/m²) and other difficult-to-machine materials. Each drill is produced entirely by grinding to ensure high accuracy and straightness of holes. Items are packaged in a rectangular plastic tube: 10 pcs for sizes 0.5–8.0 mm, 5 pcs for sizes 8.1–13.0 mm, and 1 pc for sizes 14–20.0 mm.
Advantages
Adjustable 135° point angle with chamfering improves centring and reduces walking at the start of drilling, which speeds up operations. The HSS cobalt alloy (5% Co) provides enhanced heat resistance and longer tool life when machining hard and heat-generating materials. Full grinding manufacturing ensures precise geometry and straight holes, increasing repeatability and fit accuracy. Clear plastic tube packaging keeps the drills protected and organised and indicates quantity by size.
Key specifications
Point angle: 135° (with chamfering adjustment)
Material: HSS with 5% cobalt
Temperature resistance: enhanced for high-heat applications
Suitable materials: high-alloy steels, titanium, acid-resistant and stainless steels, creep-resisting steels, cast iron (durability \> 900 N/m²), other hard-to-machine materials
Manufacturing method: entirely ground
Packaging: rectangular plastic tube; 0.5–8.0 mm — 10 pcs, 8.1–13.0 mm — 5 pcs, 14–20.0 mm — 1 pc
How to use
Select a drill size appropriate for the hole and material. Secure the workpiece and use correct clamping to prevent movement. Apply appropriate cutting speed and feed for HSS-Co drills and the specific material being machined; use cutting fluid for improved cooling and chip evacuation when drilling stainless or heat-sensitive alloys. Start at low speed to establish the centre, then increase to recommended speeds while maintaining steady feed. After drilling, clear chips and inspect hole straightness and diameter.
Recommendations
For best results with high-alloy and stainless steels, use steady coolant flow and moderate cutting speeds. Replace or regrind drills showing excessive wear or loss of geometry to maintain hole accuracy. Store drills in their plastic tubes to protect cutting edges and keep sizes organised.
