With over 25 years partnered in mandrel work, Northern's goal to supply industry grade mandrels to our customers has been a sweeping success.

Mandrel workers typically use these pieces to hold special sand paper to a roll in composite fabrication.


​We offer mandrels used to grip other moving tool components for sanding and grinding.

Northern Processes offers this guide to determine your preferred option of sand paper, backing pads, tools, flap discs, sanding screens, flap wheels, mandrels, and fiber discs for your particular application. Please read through here to give yourself a better understanding. 

There are quite a few options that allow flexibility in production that Northern Processes & Sales offers;






Auluminum Oxide TKD

PMD Supreme "Plus"

ZONE COATED

Trim Kut® Discs - Trim-Kut® is a revolutionary abrasive disc designed to grind and finish a wide variety of materials faster and cooler than any other abrasive disc available today. The patented process of fusing premium abrasive grains to a durable polymer backing results in a highly versatile grinding tool that requires no backing pad. Trim-Kut® is readily trimmable to either renew the cutting surface or reduce the diameter.


Trim Kut® Discs;


Aluminum Oxide Trim Kut Discs -

A Type represents superior grinding performance in a premium aluminum oxide resin fibre disc. A blend of advanced abrasive alloys and bonding agents delivers superior cutting rates and longer useful life. “A” Type provides optimal value when used in high stock removal applications and where a cool cutting action is required.


Aluminum Oxide Soft Metal Disc Trim Kut Discs -

SMD Type are Soft Metal Discs designed for use on soft metals like bronze, brass and aluminum. These discs disperse their own lubrication as the disc grinds, delaying heat build up of the metal work piece. Lower work surface temperature means melting is delayed, allowing the disc to cut and last longer than regular discs. The protected disc acts as an open coat shedding any buildup of debris.


Gem Supreme Trim Kut Discs - 

Zirconia/Ceramic Blend.







PMD Supreme "PLUS" Trim Kut Discs -

  • 100% Ceramic With Non-Loading Agent
  • Two top coats provide cool cutting and anti-loading on soft metals.
  • Long lasting life on aluminum and nonferros metals.
  • Out performs competitive discs 4 to 1.



PMD Supreme Trim Kut Discs - 

100% Ceramic With Top Coat.








Silicon Carbide Trim Kut Discs -

S Type Silicon Carbide is designed for stone, terrazzo, ceramic and non-ferrous metal stock removal. The highest quality Silicon Carbide is selected for this resin fibre disc.







Zee Supreme Trim Kut Discs -

100% Zirconia With Top Coat








Zirconia Trim Kut Discs -

ZEE Type represents ultimate grinding performance in a premium Zirconium resin fibre disc. The extremely hard Zirconium abrasive alloy sharpens itself in use, delivering outstanding cutting rates and maximum useful life. The advanced bond extends disc life by minimizing grain shedding, while promoting a cool grinding action which reduces glazing and loading. “Zee” type is most cost effective when used in high production application where cutting rates are monitored.


Trim Kut BRITEPREP Surface Conditioning Discs -

SURFACE CONDITIONING MATERIAL; Our high performance products are manufactured from a tight non-woven fibre web with a woven backing and impregnated with a specially processed mineral grain. They are ideal for deburring, blending coarse abrasive scratches and removing rust, corrosion, oxides, paint, adhesives and gaskets. They provide a fast initial cut and high rate of productivity. They are tough and long lasting. These discs feature our Rapid Change System with Type “R” screw on, Type “S” twist on and Hook & Loop fastening systems.

LOCKING DISCS

A NOTICE TO OUR GUESTS:

Sand paper (back-up) pads are the necessary complement to our paper. Ranging in size to match our sand paper's dimensions, we hold in stock 1"-17" pad sizes. 

Pads may be soft, medium, or hard and depending on what you are working with will determine the level of rigidness of the pad you should order, so take a look at our guide below;


PAD DENSITY;


SOFT -

● Super finishing

● Paint finishing


MEDIUM -

● Dual Action Sanding

● Hand sanding


HARD -

● Grinding

● Floor sanding


**Pads also come in low-profile, raised hubs, & high-profile.


SURFACE OF THE PAD;


HOOK -

● For velour backing sand paper


STICKY BACKING (PSA) -

● For plain paper


PLAIN BACKING -

● For stick paper (PSA)


THREAD STYLES;


ROTARY - RV - Female Threaded (N)

THREADED STUD - DV - Male threaded (R)

1)Loop (Velour) backing paper


This paper is generally the go-to in the industry. Current trends favor this over PSA as it is quickly applied and released by pulling from the hook (velcro backed) pad. Generally much tougher than our plain and PSA options.
