MS310 STIHL Chainsaw Attachments, Hammer Drill Prices, and Shop Basics That Actually Matter

The Short Version

If you are keeping an old MS310 STIHL chainsaw in service, the most useful upgrade is not a bolt-on attachment. It is a sharp chain, a bar that matches the saw housing and sprocket, and a tensioner that actually holds. I have seen crews lose half a day because the chain was installed backwards, or because they bought a bar with the wrong tail mount and tried to blame the saw.

And if your job today involves fixing things around the shop, here are the quick answers. Hammer drill price in early 2025 is roughly $70 to $140 for a corded unit, $120 to $220 for a brushless cordless bare tool, and $250 to $450 for a kit with batteries. A drive bolt biter impact extraction socket set is one of those tools you do not think about until a rounded bolt stops the job. And what is standard door hinge size? For most interior residential doors it is 3.5 by 3.5 inches. Exterior doors often use 4 by 4 inches. Measure before ordering.

Why I Am Writing This From the Repair Bench

In my role coordinating repairs for landscape crews and rental-fleet customers, I have handled a few hundred rush jobs over the last six years. When I am triaging a request, I do not ask what gadget looks cool. I ask how many hours until the crew needs it running. In March 2024, a landscaping company called at 7 a.m. with a saw that would not start and a fence job starting at 9. Normal turnaround at the shop is two days. We found a worn fuel line, paid $45 extra for a courier to bring the part, and the saw was cutting by 10:15. The alternative was a $500 rental and losing the job.

That experience biases me toward simple, field-serviceable tools. I don't have hard data on how many MS310s are still in service, but based on the steady stream of parts orders we send, my sense is there are still thousands earning money every week.

STIHL MS310 Chainsaw Attachments: The Part That Actually Matters

The STIHL MS310 is a 59cc mid-size work saw. It isn't the newest model in the lineup anymore, but plenty of them are still running. The problem is that when people search for 'stihl chainsaw attachment,' they often end up looking at hedge trimmers and pole pruners for STIHL's multi-tool system. That's the wrong system. The MS310 uses a traditional guide bar and chain. The first thing to think about is the bar-and-chain combo and the sprocket driving it.

Before you order anything, read the numbers stamped on the side of the bar. The MS310 has been sold with different bar lengths, pitches, and drive-link counts over the years. If you assume one 'fits MS310' is the same as another, you can waste a day. In my first year, I made the classic rookie mistake of ordering a chain by saw model without checking pitch and drive links. It didn't fit, cost me a restocking fee, and taught me a lesson the hard way. The model number is a starting point, not a guarantee.

What I'd actually buy first is a good sharpening kit and an extra chain. A sharp chain is the difference between a 30-second cut and a three-minute fight. I would also replace the sprocket when you replace the chain. A worn sprocket will ruin a new chain quickly. Keep the bar oil reservoir full, clean the groove, and check the tension before every start. Those basics are the real 'chainsaw attachment' to the machine.

What I mean by 'stihl chainsaw attachment' is not a single part. It is a system: bar, chain, sprocket, oiler, tensioner. Get the system right and the saw will outwork you. Get one piece wrong and you'll be back in the shop.

Hammer Drill Price: Early 2025 Reality Check

If you need to drill into masonry or concrete occasionally, you don't have to spend a fortune. Based on retail listings I checked in early January 2025, street prices look like this. A corded 1/2-inch hammer drill from a known brand runs about $70 to $140. A brushless cordless hammer drill as a bare tool runs $120 to $220. With a battery and charger, expect $250 to $450. A true rotary hammer with SDS-Plus bits runs $150 to $400 for a decent unit.

Why does the distinction matter? Because a hammer drill is not the same as a rotary hammer. A hammer drill chips and hammers while spinning, but it is not designed for a full day of concrete work. A rotary hammer has a heavier impact mechanism and is the right tool for drilling anchors in a foundation wall. For occasional jobs, a corded hammer drill is still a pretty good value. For regular concrete work, rent or buy a rotary hammer.

In 2020, I would have told you to buy corded if you wanted dependability. In 2025, I would say a brushless cordless hammer drill is enough for most field repairs. The fundamentals haven't changed, but the execution has.

Drive Bolt Biter Impact Extraction Socket Set: Buy It Before You Need It

Honestly, I was skeptical the first time I used a drive bolt biter impact extraction socket set. It looks like a socket with aggressive spiral teeth inside. You tap it onto a bolt head that someone already rounded off, put an impact driver or ratchet on it, and the teeth bite into the metal as you turn. One day a rounded bolt on a trailer hitch stopped a job for twenty minutes. One socket, an impact driver, and it was out. Exactly what we needed.

A decent set runs about $25 to $55, and it's one of those things that feels unnecessary until it saves a piece of equipment. This is not a magic removal tool. It won't help if the bolt head is rusted away, and it cannot fix a bolt that is broken off flush. But for rounded hex heads on chainsaw parts, mower decks, and hardware, it is a no-brainer.

One warning: if you use an impact wrench, buy the impact-rated version of the set. A standard chrome socket can crack when it is hammering and twisting at the same time. For me, a socket that is not rated for impact use is a deal-breaker.

What Is Standard Door Hinge Size? The Short Answer, Then the Catch

For most residential interior doors, the standard door hinge size is 3.5 by 3.5 inches. For heavier exterior doors, it is often 4 by 4 inches or 4 by 3.5 inches, depending on door weight and manufacturer. But here is the catch. The corner radius matters too. A hinge with square corners will not seat properly in a door mortise routed for radius corners, and a radius corner hinge on a square-corner prep will bind or look wrong.

I learned that the hard way. I assumed the hinge size on an exterior door was the same as an interior door. Didn't verify. The previous contractor had used 4-inch hinges on a 3.5-inch hinge prep, and the door was carrying weight on screws that were not in the right place. The door worked, but it was not right. Now I measure the hinge leaf and the corner radius before ordering anything.

If you are replacing a hinge, take a photo of the hinge on the door and measure the screw hole spacing. That will tell you more than the word 'standard' ever will.

Where This Advice Stops Applying

My experience is based on repair-shop and field work with landscape, construction, and rental clients in one region. If you are doing full-time commercial felling or drilling into concrete all day, your needs are different. The price ranges above are planning numbers, not promises. Check current listings before you buy.

And don't take 'standard' as a license to skip measuring. A MS310 bar and chain need to match each other. A door hinge needs to match the prep. An extraction socket needs to match the rounded bolt size. The tools are not complicated, but they are not universal either.

Bottom line: keep the basics sharp, buy the extraction socket set before you need it, and don't trust a model number or a hinge size until you have measured the thing in front of you.
