With a DIN338 industrial standard, the Tolsen 75117 uses M2 steel for drilling through carbon steel and alloys. Fully ground spirals evacuate debris during high-speed rotation. This 5mm jobber length bit resists heat buildup during continuous use.
Key Features
- 130° Split Point: Self-centering geometry stops the bit from walking on smooth surfaces. Starts holes exactly where placed.
- 3-Flatted Shank: Three flat surfaces provide a mechanical lock in the chuck. Stops bit spinning under torque.
- Black and Gold Finish: Surface treatment reduces friction and dissipates heat during drilling. Resists rust in high local humidity.
- M2 Steel Grade: Fully ground high-speed steel maintains a sharp cutting edge. Drills through wood and metal.
- Standard Dimensions: 52mm flute length with an 86mm total bit length. Prevents clogging when drilling deep holes.
Frequently Asked Questions
What is a 130 degree split point drill bit used for?
The 130° point geometry bites into metal immediately without a pilot hole. This design stops the bit from wandering across smooth surfaces.
Is Tolsen 75117 suitable for stainless steel?
M2 steel grade handles stainless steel and other hard alloys without dulling quickly. Cutting oil helps manage heat during high-load drilling.
