MicroJIG Kerf Splitter Steel PRO Kits (SP-2 & SP-2TK)

Regular price $39.90

The MicroJIG Splitter SteelPro greatly improves safety by reducing the occurrence of kickback from both sides of the saw blade. The double-splitter technique offers a unique approach to table saw safety. By placing two splitters back-to-back behind the saw blade, the SteelPRO System allows the user to offset one splitter towards the fence to control the keeper-piece and offset the other splitter away from the fence to control the off-cut piece. The MJ Splitter SteelPRO System is available for 1/8” kerf saw blades and thin kerf saw blades. The SteelPRO System can be easily installed into a Zero Clearance Throat plate on most table saws. Installation is so simple, it´s foolproof.

The SteelPRO uses a stainless steel core coated with high density plastic for significantly improved durability and resilience.

This new splitter system utilizes a patented "Automatic Kerf Keeper”. The Kerf Keeper is a separated tab installed behind one of the SteelPRO Splitter inserts that is automatically ejected from its station once the saw kerf begins to close. A closing saw kerf posses a great danger to the user because the board may bind the saw blade and kickback. The Automatic Kerf Keeper deploys when the board pinches the Kerf Keeper and pulls it out of its position. Not only does this keep the kerf wedged open, it signals to the user the kerf is closing and the saw should be turned off.

Please note: The Full Kerf version is for 1/8" thick blades and the Thin Kerf version is for less than 1/8" kerf blades. Both are to be used when making 90° cuts only.

Both Kits Include:

  • One drill guide
  • One 3/16" drill bit
  • Four MJ Splitter SteelPRO inserts
  • Three Automatic Kerf Keepers
  • Five #8 x 1/2" washer head wood screws
  • Installation instruction sheet
  • Warranty registration card

Woodworking Safety Day. Woohoo, let's celebrate. Oh, wait. Today is not a holiday, but a reminder to take the time and go out to your shop and make sure you are using the best possible practice in your safety procedures.

Shop Safety is something we at Infinity Cutting Tools take seriously because almost every woodworker has a story of what happened to them or a friend, yet we all still go and rush through a project or two. All the stories talk about how it happened so quickly, yet we are sure that it will never happen to us.

My worst injury came on a miter saw. I was cutting radius stops for an arched-top radius door. I had done this hundreds of times. You lay your curved profiled piece of wood against the fence and figure out your angle. You lay some scrap blocks on the back of the curve to keep it from getting pulled or yanked. Yup. I was in a hurry and decided that the little bit I was cutting wouldn't need a backer block. When the blade hit the radius stop, it jerked it through the palm of my hand and I had an awesome cut through my fingers and palm. I was out of work for a few weeks. Let's celebrate.

Injuries do happen. They are almost always preventable. Best Possible Practices. What I mean by this is go out and do what you know you need to do to be safe in your shop. We know we need our safety glasses or over-the-glasses safety glasses. We know we need ear protection. We know we should use dust masks and/or respirators. Wear them. Use them.

Why did no one tell me I looked this silly.  No, I don't really wear my mask unless I'm spraying finishes or fighting crime, but I do wear my safety glasses at all times and wear ear protection for anything loud.

We want to talk about some of the easy things you can do to be safe.

  • Keeping your tools sharp. A sharp tool is much safer as it requires less energy to push wood through.
  • Tuning up your equipment. Make sure fences are square and belts are tight. Every now and then go through and tighten bolts.
  • Table Saw Safety. Use a riving knife or splitter on the table saw.
  • Electrical Safety. Unplug equipment when you are working on it.
  • Sixth Sense. If you think you shouldn't do something, don't do it.
  • Take Your Time. Don't rush woodworking. Enjoy it.
  • Use Safety Equipment. Use jigs, push sticks, sleds, and featherboards to keep your little fingers away from the sharp, pointy stuff.

Best. Possible. Practice. It only takes a minute.


Frequently Asked Questions

How does the SteelPRO splitter reduce kickback?

It uses a double-splitter technique: two splitters mounted back-to-back behind the blade, one offset toward the fence to control the keeper-piece and one offset away to control the off-cut. This controls both sides of the cut. See more table saw accessories.

What is the difference between the SP-2 and SP-2TK kits?

The Full Kerf version (SP-2) is for 1/8" thick blades, while the Thin Kerf version (SP-2TK) is for blades with a kerf thinner than 1/8". Choose the one that matches your saw blade.

What is the Automatic Kerf Keeper?

It is a patented separated tab installed behind one of the SteelPRO inserts. When the saw kerf begins to close and pinches the tab, it is automatically ejected, which keeps the kerf wedged open and signals you to turn off the saw.

Will the SteelPRO fit my table saw?

The SteelPRO system can be easily installed into a zero-clearance throat plate on most table saws. The included drill guide and 3/16" drill bit make installation straightforward.

What comes in each kit?

Each kit includes one drill guide, one 3/16" drill bit, four MJ Splitter SteelPRO inserts, three Automatic Kerf Keepers, five #8 x 1/2" washer-head wood screws, an installation instruction sheet, and a warranty registration card.

Can I use the splitter for angled or bevel cuts?

No. Both the Full Kerf and Thin Kerf versions are designed to be used when making 90° cuts only.

What is the splitter made of?

The SteelPRO uses a stainless steel core coated with high-density plastic, which significantly improves its durability and resilience compared with all-plastic splitters.

Is the SteelPRO hard to install?

No. MicroJIG describes the installation as so simple it is foolproof. The kit includes a drill guide and drill bit to position everything accurately in a zero-clearance throat plate.

Why is a closing kerf dangerous?

A closing saw kerf can cause the board to bind the saw blade, which leads to kickback. The Automatic Kerf Keeper helps by holding the kerf open and alerting you to stop. Pair the splitter with push blocks & featherboards for added safety.

Who makes the SteelPRO splitter system?

It is made by MicroJIG, which engineered the double-splitter SteelPRO system and the patented Automatic Kerf Keeper for improved table saw safety.
