Anti-Skive Drill Bit - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240033833 titled 'Anti-Skive Drill Bit

Simplified Explanation

The abstract describes an anti-skive drill bit that has a body with a proximal end, a distal end, and a flute extending along the body. The distal end includes a relief surface and a first channel surface. The relief surface has a first most-distal point at the intersection of the body's outer diameter and the leading edge of the first flute, as well as the intersection of the body's outer diameter and the first channel surface. The relief surface angle between the relief surface and the body's outer diameter surface at the first most-distal point is less than 90 degrees. The first channel has a proximal end intersecting the first flute and a distal end intersecting the relief surface.

  • The anti-skive drill bit has a flute that extends along its body.
  • The distal end of the drill bit includes a relief surface and a first channel surface.
  • The relief surface has a first most-distal point at the intersection of the body's outer diameter and the leading edge of the first flute, as well as the intersection of the body's outer diameter and the first channel surface.
  • The relief surface angle between the relief surface and the body's outer diameter surface at the first most-distal point is less than 90 degrees.
  • The first channel has a proximal end that intersects the first flute and a distal end that intersects the relief surface.

Potential applications of this technology:

  • Drilling in materials that are prone to skiving or tearing.
  • Precision drilling in delicate materials.
  • Creating clean and accurate holes in various materials.

Problems solved by this technology:

  • Minimizes skiving or tearing of materials during drilling.
  • Reduces the risk of damage to delicate materials.
  • Improves the accuracy and cleanliness of drilled holes.

Benefits of this technology:

  • Increased efficiency and productivity in drilling operations.
  • Improved quality and precision in hole creation.
  • Reduced material waste and rework.
  • Enhanced durability and longevity of the drill bit.


Original Abstract Submitted

an anti-skive drill bit including a body having a proximal end, a distal end, a longitudinal axis extending between the proximal and distal ends, and a flute extending longitudinally along the body. the distal end includes a distally facing region and a first channel defining a first channel surface. the distally facing region includes a relief surface having a first most-distal point at one of an intersection of an outer diameter of the body and a leading edge of the first flute, and an intersection of the outer diameter of the body and the first channel surface. the distally facing region has a relief surface angle between the relief surface and an outer diameter surface of the body at the first most-distal point of less than 90 degrees. the channel has a proximal end intersecting the first flute, and a distal end intersecting the relief surface.
