About MMP

Managed by people who've spent their careers under the tolerance stack

Mack Machine Products Pvt. Ltd. (MMP) is a reliable manufacturer of drill bushings with expertise in both metric and imperial standards. Alongside bushings, we manufacture a range of high-precision production components — honing, grinding, custom parts and industry-standard parts are the core of what we do.

Every bushing is made to precise geometry and a fine surface finish, which means a longer life for the tools that run against it — less downtime, lower labour cost, and more throughput for the shops that use them.

We're equipped with the machines and metrology the precision engineering industry demands, run by a management team that's professional and dependable, and a skilled, motivated workforce that's the real backbone of the organisation. It's this combination that's taken our FALCON brand of bushings from India to customers worldwide.

Why MMP

Four things we don't compromise on

Superior Quality

ID honed, OD ground, and checked on our own metrology floor before it ships — bore and OD held to as fine as 4 microns.

Competitive Prices

Precision doesn't have to mean a premium quote. We price to be your reliable, cost-effective source — not the expensive one.

Delivery Commitment

We quote a date and we hold it. Production is planned around your deadline, not the other way round.

Reliable, Quick Response

A question about a drawing or a tolerance gets answered by someone who actually runs the machine.

Products

Two product lines: standard tooling, and drawing-built components

From off-the-shelf drill bushings that keep jigs and fixtures running, to precision components turned, honed and ground to a customer's own drawing.

Standard drill bushings

Standard Bushings

Headless and head press-fit bushings in stock ranges, to Indian and ANSI/imperial sizing.

Special bushings and precision pins

Special Bushings

Custom geometries, guide pillars, gauges and pins built to a customer's drawing.

Automotive and production components

Automotive & Production Components

Piston pins, spools, pistons and cylindrical parts machined for OEM supply lines.

Drill bushing types — ANSI standard

Our core drill bushing range, built to ANSI bore, tolerance and concentricity specifications.

Type P
HEADLESS PRESS FIT

Flush-mounted press-fit bushing with no head, for applications where clearance is tight.

Type P-TW
HEADLESS, THIN WALL

Same flush fit, thinner wall for a larger bore within the same outer diameter.

Download PDF
Type H
HEAD PRESS FIT

Press-fit bushing with a head that seats against the jig plate for a positive stop.

Download PDF
Type H-TW
HEAD, THIN WALL

Head press-fit in a thin-wall body, for a larger bore without oversizing the OD.

Download PDF
Type SF
SLIP FIXED RENEWABLE

Renewable bushing that locates in a liner and can be swapped out as it wears.

Manufacturing Capabilities

What we can typically hold — on our own floor

MMP runs its own honing, grinding and turning floor, backed by in-house metrology. Below is a quick snapshot of our standard capability; for anything outside these ranges, send your drawing and we'll confirm.

1.5–120 mm
Bore size, honed / ground
Smallest finished bore is 1.5 mm; beyond 120 mm needs individual reference.
4 microns
Bore & OD tolerance
Generally achievable; finer tolerances on individual reference.
5 microns
Concentricity
Subject to certain conditions; tighter values on reference.
0.4 Ra
Surface finish
Honed or ground; finer finishes on individual reference.
5 microns
Best parallelism
Subject to certain conditions.
IS 2102-II
Open tolerance, unfinished dims
Medium class, for turned / milled / drilled portions.
