The Tolsen 75123 8mm HSS Jobber Drill Bit bores through industrial-grade metal, wood, and plastic. Fully ground M2 high-speed steel maintains sharp cutting edges under heavy friction. This version improves on the 118° predecessor with a 130° split point and replaces the polished finish with a friction-reducing black and gold oxide coating.
Key Features
- 130° Split Point: Self-centering geometry prevents bit walking on smooth metal surfaces. Starts holes instantly.
- Black & Gold Oxide: Dual-layered finish sheds heat to prevent bit tempering. Reduces friction during high-speed drilling.
- M2 Steel Grade: High-carbon alloy construction resists deformation during heavy-duty industrial cycles. Holds edges longer.
- Straight Shank Design: 8mm diameter fits standard keyed or keyless chucks in BD workshops. Ensures compatibility.
- Fully Ground Flutes: Precision-machined spirals clear chips quickly to prevent bore clogging. Maintains drilling speed.
- 10-Piece Bulk Pack: Industrial quantity of ten 8mm jobber length bits. Lowers cost per unit for production lines.
Frequently Asked Questions
What is a 130 degree split point drill bit used for?
This tip design starts drilling on contact without a pilot hole. It stops the bit from sliding across the workpiece surface.
Is Tolsen HSS drill bit good for stainless steel?
The M2 grade steel cuts stainless steel if you use proper lubrication and low speeds. High friction without cooling will burn the tip.
What does jobber length mean?
This refers to a standard length bit where the flute length is approximately 9 to 14 times the diameter. It provides the best balance for general-purpose drilling tasks.
