Tolsen 75108 Black and Gold HSS Drill Bit 2.5mm penetrates dense alloys using M2 high-speed steel. Under pressure, the 130-degree split point stops the bit from walking across smooth metal. Following DIN338 standards, this bit maintains hole alignment during repetitive industrial drilling.
Key Features
- 130° Split Point: Self-centering geometry prevents surface walking. The tip bites into metal instantly without needing a pilot hole.
- Black and Gold Finish: Titanium Nitride surface reduces friction heat. Resists wear during high-RPM drilling in humid Bangladesh workshops.
- M2 High Speed Steel: Industrial-grade alloy construction. Retains a sharp cutting edge through repeated penetration of hard materials.
- Jobber Length: 57mm total length with a 30mm flute. Provides rigidity to prevent snapping under heavy lateral pressure.
Frequently Asked Questions
What is a 130 degree split point drill bit used for?
It centers itself on metal surfaces to prevent the bit from wandering. This geometry removes the need for a center punch before drilling.
Can Tolsen HSS bits drill through stainless steel?
M2 grade high-speed steel penetrates stainless steel plates. Using cooling oil prevents the bit from burning out at high speeds.
