CT COUNTERSINK, #6 SCREW

UPC: 738685952047 SKU: Amana 55204 Categories: Amana Tool, Boring & Drilling Bits, Carbide Tipped Countersinks Bits, Countersink Bits

Item Description

Used to countersink holes for the heads of screws in woods, plastic and non-ferrous materials. The 2-flute integral design ensures uniform and concentric results each and every time. Carbide tips provide chip free hole edges and lasts much longer than steel countersinks.

Available in a wide variety of sizes, complete with the HSS M2 fully ground drill bit.

Excellent for Drilling:

Natural Woods
Man-Made Boards
MDF
Chipboard
Plywood
Aluminum/Non-Ferrous
Aluminum Composite Material (ACM)
Composites
Composite Decking Materials
High Density Polyethylene (HDPE)
Acrylic

Warning:** When drilling aluminum/non-ferrous materials, for optimal results and extended tool life use lubricant or air cooling. Make sure the material is fixed and drill is stable during drilling.

CNC Countersink

Drilling countersinks with these bits on the CNC machine is a great way to save time and have your pieces look great every time!

With the adjustable depth drill bit you can adjust them for whatever size material you’re working with. They are best used with a drilling toolpath, utilizing the peck drill option at .25″ per pass with a .125″ retract height.

For best results run at 3,000 RPM with a 30 IPM (Inches Per Minute) plunge rate. No feed rate needs to be set with these as they only move up and down with the Z axis, not side to side. If your software doesn’t allow a 0 feed rate, you can enter 1 IPM(Inch Per Minute) in the feed rate as a placeholder.

For countersinks with 1/4″ round shank, use 1/4″ spring collet.

For countersinks with 5/16″ round shank, use 7-8mm spring collet.

For countersinks with 3/8″ round shank, use 9-10mm spring collet.

Need This Tool Customized?

Every machining application is different. If this tool is close to what you need but not an exact fit, General Cutting Tools can help modify it for your specific job, machine, material, or production requirement.

We work with CNC shops, industrial manufacturers, tool rooms, and production facilities to provide tool modifications that improve fit, function, performance, and efficiency. Whether you need a small adjustment or a more specialized cutting tool solution, our team can review your requirements and recommend the best option.

Custom tool modifications can help reduce setup time, improve accuracy, extend tool life, solve clearance issues, and support more consistent production results.

Common Tool Customization Options

Diameter and OD Modifications

We can modify tool diameters to better match your application requirements, including cutting diameter changes, OD modifications, pilot diameter adjustments, step diameters, and shank diameter modifications.

Bore Modifications for Saw Blades

Custom saw blade bore modifications are available for hole diameter changes, pinholes, mounting holes, and keyway cutouts to help match your machine setup and cutting requirements.

Length Adjustments

Tools can be modified for specific reach, clearance, or setup needs. This may include overall length changes, flute length adjustments, reduced neck sections, extended reach designs, or shortened tools for improved rigidity.

Shank Modifications

Shank modifications can help ensure the tool fits properly in your holder, spindle, or machine setup. Common options include shank diameter changes, flats, Weldon flats, reduced shanks, and custom holding requirements.

Radius, Chamfer, and Corner Changes

We can customize corner radius, chamfer angles, edge breaks, and other profile details to meet part print requirements or improve cutting performance.

Step Tool Modifications

For applications that require multiple diameters or operations in a single tool, we can create or modify step tools to help reduce tool changes and improve production efficiency.

Flute and Cutting Edge Adjustments

Depending on the tool and application, flute length, cutting edge geometry, end cutting features, relief angles, and cutting edge shape may be modified to improve chip evacuation, cutting action, and tool performance.

Regrinding and Resharpening

Many cutting tools can be reground or resharpened to restore performance, extend tool life, and reduce replacement costs.

Custom Profiles and Special Forms

For unique part features, we can help provide special forms, custom profiles, custom radii, counterbores, countersinks, keyseat cutters, form tools, and other application-specific tooling solutions.

Material-Specific Tool Adjustments

We can help modify or recommend tooling based on the material being machined, including aluminum, brass, bronze, plastics, stainless steel, hardened steel, cast iron, composites, and other industrial materials.

Have a Drawing, Sample, or Part Print?

Send us your print, sketch, CAD file, photo, tool number, sample, or application details. For the fastest quote, include the material being cut, quantity needed, required dimensions, tolerances, and any machine or holder requirements.
