Picking the Correct Countersink for Your Next Job

What are Countersinks Used for?champion_Countersinks

A countersink is a cutting tool that cuts a conical hole into a base material and can be used for a number of different applications. The main use of countersinks is to cut a hole to allow the head of a countersunk screw or bolt, when fastened into the hole, to sit below or flush with the surface of the base material. They are also used after drilling and tapping applications to remove any burrs that are left behind.

Why Choose Champion Countersinks?

Champion Cutting Tool manufactures a wide variety of high-speed steel countersinks designed to perform a number of different applications, each with their own advantages in certain situations. Champion’s countersinks will provide users with a chatter-free performance and smooth, fast chip removal. Countersinks can be used in hand drills, drill presses, milling machines and lathes. Widely used in the glass, window and door industry, Champion countersinks will cut through metal, plastic and wood.

Most Popular Countersink Styles

Zero Flute Countersinks

Zero Flute Countersink
Zero Flute Countersink

Zero flute countersinks are a cross-hole countersink, the cone-shaped cutting tools feature a cutting edge provided by a hole that goes through the side of the cone. The cutting edge is formed from the intersection of the hole and the cone. Commonly referred to as a Weldon style countersink. Zero flute countersinks are best suited for softer materials including aluminum, wood & plastic for countersinking & deburring applications. They are offered in 2 styles:

  • Piloted: Piloted countersinks are recommended for screws from 1/4″ – 1/2″ diameter
  • Pilotless: Pilotless countersinks are recommended for bolt sizes from 0.073″ – 1-15/32″ & screw sizes #4 – #10 diameters

Single Flute Countersinks

Single Flute Countersink

Single flute countersinks are designed for use when the hole is too small for a multi-flute countersink or when multi-flute countersinks chatter. Widely used for machine and portable work at high speeds.

Three & Four Flute Countersinks

Similar to single flute countersinks, multi-flute countersinks are designed for chatter-free performance and are mostly used in portable applications.

Combo Drill & Countersinks

Multi Flute Countersink
Multi Flute Countersink

Combo drill and countersinks are designed to produce accurate conical holes in components that require machining between centers.

How to Choose the Right Size Countersink Diameter

You will want to choose a countersink that is larger than the bolt size of the hole. Countersink diameter = 1.5 x Bolt Size Hole Diameter.

Example: 1/4″-20 Bolt – Multiple the diameter (.250) x 1.5 = 0.375. You will want to use a 3/8″ countersink.

How to Calculate Countersink RPM Speeds

Countersinking is typically performed at 1/3 of the RPM speed of drilling. You will first want to calculate the speed by using the formula below, then you will want to divide that speed by 3 to get the countersinking speed.

Formula: SFM (surface feet/minute) x 3.82 / Cutter Diameter (decimal equivalent) / 3

Material Surface Feet / Minute (SFM) Sample Calculations for 1/4” Countersink Speed (RPM)
Aluminum 200 – 250 (225 (SFM) x 3.82 / .2500) /3 = 1,146 RPM
Mild Steel 100 – 110 (115 (SFM) x 3.82 / .2500) /3 = 586 RPM
Stainless Steel 30 – 100 (65 (SFM) x 3.82 / .2500) /3 = 381 RPM

What is a Jobber Drill?

What Does the Term “Jobber” Mean?

The general definition of the term “jobber” is “a person or company that buys from manufacturers and sells to retailers”, most commonly used in the 1850-1950 period. At that time, manufacturers were mostly producing general purpose “for the trade” drill bits, not using specialized machining applications to make specific lengths or designs like today. These drills, were of medium length and suitable for a wide variety of jobs, coining the term “jobber-length”, reflecting the same concept of terms like “general purpose” and “multipurpose”. Today, jobber drill refers to the length of the drill itself.

What is a Jobber Drill?

Today Jobber Drills are manufactured in a number of different style to tackle a number of different applications. Jobber Drills still remain the most commonly found type of drill bit. A jobber drill bit has a long length compared to its diameter. The length of the flute is between 8-12 or 9-14 times the diameter of the drill, depending on the drill specifications. For example, a 1/2″ diameter jobber drill will be able to drill a 4-1/2″ deep hole because it is 9 times the diameter in length. Jobber drills are measured using a number of different systems:jobberDrills

  • Fractional Sizes
  • Letter Sizes
  • Wire Gauge Sizes
  • Metric Sizes
The size and measurement system you choose will depend on the application for which the drill will be used.

Champion Cutting Tools’ Carbide Burs are Now Available Online at Tannerbolt.com

One of the most versatile and widely used metalworking tools is the carbide bur. Carbide burs are used for numerous applications including weld preparation/smoothing, deburring, chamfering, pattern making, die sinking, toolmaking, and much more. Champion Cutting Tools’ line of high-quality carbide burs are designed and made to handle even the most demanding jobs. Champion’s carbide burs are manufactured in the U.S.A. from C2 tungsten carbide. They are precision machine ground using diamond wheels and automated CNC machinery. This manufacturing process produces consistent geometry, sharp cutting edges, and vibration-free performance. A Titanium Nitride coating is added to all carbide burs to provide a superior finish and a longer life, all at no extra cost to you the customer. At Tanner, we offer numerous shapes of carbide burs including SA – cylinder shape, SB – cylinder end cut, SC – cylinder radius end, SD – ball shape, SE – oval shape, SF – tree shape radius end, SG – tree shape, SH – flame shape, SJ – 60-degree cone shape, SK – 90-degree cone shape, SL – 14-degree taper radius end, SM – cone shape, and SN – inverted cone shape. We also offer two different types of cuts, Double Cut and Non-Ferrous, as well as Long Series carbide burs.

For more information about Champion’s Carbide Burs shapes, sizes and cutscheck out the Carbide Burs PDF here

Important tips on using and selecting the correct carbide bur:

  • The selection of shape and diameter is based on the workpiece and application.
  • Tanner offers the following carbide bur shapes: SA – cylinder shape, SB – cylinder end cut, SC – cylinder radius end, SD – ball shape, SE – oval shape, SF – tree shape radius end, SG – tree shape, SH – flame shape, SJ – 60-degree cone shape, SK – 90-degree cone shape, SL – 14-degree taper radius end, SM – cone shape, and SN – inverted cone shape.
  • The selection of cut is based on the material and finish required.
  • Double Cut burs have teeth that provide excellent stock removal on hard materials. They reduce bounce and chatter, offer excellent operator control, and produce a fine surface finish
  • Non Ferrous burs are recommended for soft materials that tend to load and pack in the flutes. These burs have open, aggressive cutting edges that allow easy chip flow and minimal clogging.
  • When using carbide burs, start at lower speeds and increase speed until the desired result is achieved.
  • When placing the carbide bur into the die grinder, it should be inserted into the collet as far as possible to minimize overhang.
  • Carbide burs should be feathered into the cut with even pressure to avoid digging into the material.
  • Do not apply excessive pressure, it can slow the spindle and chip cutting edges. Let the bur do the cutting.
  • Never encapsulate the bur in the cut.
  • Carbide burs, if used properly, will outperform HSS burs by 50:1.
